BPC-157 is a synthetic pentadecapeptide whose sequence is commonly given as Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. It is described in the literature as a fragment of a larger protein found in human gastric juice, referred to as body protection compound. The peptide was first characterized in the early 1990s by a research group in Zagreb, Croatia. Its molecular formula is C62H98N16O22 and its monoisotopic mass is approximately 1419 daltons.
Supplied material is typically a lyophilized white to off-white powder. The peptide is freely soluble in water and in common aqueous buffers, which allows it to be handled as a stock solution. Because the sequence contains no cysteine, disulfide cross-linking is not a route of degradation. The absence of aromatic residues means ultraviolet absorbance at 280 nm is minimal, so quantification usually relies on peptide bond absorbance near 214 nm or on amino acid analysis.
BPC-157 is a synthetic peptide composed of fifteen amino acids. Its sequence corresponds to part of a protein found in human gastric juice, which is the origin of the "body protection compound" label. In laboratory work the material is treated as a defined research chemical rather than a finished product. Published research has centered on animal models, and the peptide is not an approved medicine in most countries.
The peptide was first described in the early 1990s by a group studying gastric secretions and tissue repair. Its fifteen-residue chain is usually written as GEPPPGKPADDAGLV in single-letter code. The free peptide has the formula C62H98N16O22 and a theoretical mass near 1419.5 daltons. These identifiers are established chemical facts that can be checked against standard peptide databases. There is no ambiguity about the primary structure.
| Property | Value | Notes |
|---|---|---|
| Appearance | White to off-white lyophilized powder | Assessed by visual inspection under ordinary laboratory lighting |
| Molecular mass | Approximately 1419 Da | Monoisotopic mass for the fifteen-residue sequence |
| Solubility class | Freely soluble in water | Stock solutions commonly prepared in water or aqueous buffer |
| Typical storage temperature | -20 °C or below, desiccated | Lyophilized powder; repeated freeze-thaw cycles are usually avoided |
| Common analytical method | Reversed-phase HPLC with UV detection | Frequently paired with mass spectrometry to confirm identity |
Long-term storage of the dry powder is typically described at minus twenty degrees Celsius or colder, while shorter holding periods may use ordinary refrigeration. Repeated warming and cooling cycles are discouraged because they stress the material and can promote aggregation or loss. Light exposure and residual moisture are both treated as avoidable sources of degradation, and working aliquots are often prepared to limit how many times a container is opened. Sealed vials with a desiccant are the usual container.
Quality assessment rests on two separate questions: whether the chain is the intended one, and how much of the sample is that chain. Reverse-phase high-performance liquid chromatography with ultraviolet detection is the standard purity measurement, while mass spectrometry confirms identity through the observed molecular mass. Amino acid analysis and sequence verification provide further checks. A reported purity percentage describes the proportion of the sample represented by the main peak, not the amount of peptide by mass, since counter-ions and water make up part of any lyophilized lot.
Evidence in humans is limited. Small clinical studies have examined the peptide in contexts such as ulcerative colitis and wound healing, but participant numbers are small and independent replication is scarce. It is not approved as a medicine by major regulatory agencies and is distributed mainly as a research material or compounded preparation. Long-term human safety data are not established, and questions about absorption through non-injected routes remain open rather than resolved. Claims about its effects are best read against these gaps.
BPC-157 is a synthetic peptide of fifteen amino acids, written in single-letter code as GEPPPGKPADDAGLV. The sequence corresponds to a partial fragment of a protein isolated from human gastric juice, described in early reports as body protection compound. The number 157 refers to a fragment designation in that work rather than to molecular mass. Initial descriptions appeared in the early 1990s, when the fragment was reported to protect gastrointestinal tissue in animal models. Commercial material is produced by solid-phase peptide synthesis rather than extracted from biological sources.
Laboratory research on this peptide has examined a wide and heterogeneous set of endpoints, including gastric ulcer models, tendon and ligament injury, wound closure, and intestinal inflammation. Most published findings come from rodent studies, and reported effect sizes are often large relative to controls. Because the compound has been tested across many unrelated injury models, the literature is frequently described as unusually broad for a single peptide. A substantial share of this work originates from a small number of research groups, which matters when assessing how widely results have been reproduced.
=== Breastfeeding === In 2016, estimates suggested that more widespread breastfeeding could prevent about 823,000 deaths annually of children under age 5. In addition to reducing infant deaths, breast milk provides an important source of micronutrients - which are clinically proven to bolster children's immune systems – and provides long-term defenses against non-communicable and allergic diseases. Breastfeeding may improve cognitive abilities in children, and correlates strongly with individual educational achievements. As previously noted, lack of proper breastfeeding is a major factor in child mortality rates, and is a primary determinant of disease development for children. The medical community recommends exclusively breastfeeding infants for 6 months, with nutritional whole food supplementation and continued breastfeeding up to 2 years or older for overall optimal health outcomes. Exclusive breastfeeding is defined as giving an infant only breast milk for six months as a source of food and nutrition. This means no other liquids, including water or semi-solid foods.
Moreover, the Court of Justice has clarified that its recognition of rights was 'inspired' by member states' own 'constitutional traditions', and international treaties. These include rights found in member state constitutions, bills of rights, foundational Acts of Parliament, landmark court cases, the European Convention on Human Rights, the European Social Charter 1961, the Universal Declaration of Human Rights 1948, or the International Labour Organization's Conventions. The EU itself must accede to the ECHR, although in Opinion 2/13 the Court of Justice delayed, because of perceived difficulties in retaining an appropriate balance of competences.
Due to their higher levels of androgen exposure during fetal development, the female hyenas are significantly more muscular and aggressive than their male counterparts; social-wise, they are of higher rank than the males, being dominant or dominant and alpha, and the females who have been exposed to higher levels of androgen than average become higher-ranking than their female peers. Subordinate females lick the clitorises of higher-ranked females as a sign of submission and obedience, but females also lick each other's clitorises as a greeting or to strengthen social bonds; in contrast, while all males lick the clitorises of dominant females, the females will not lick the penises of males because males are considered to be of lowest rank. The female spotted hyenas urinate, copulate and give birth through the clitoris since the urethra and vagina exit through the clitoral glans. This trait makes mating more laborious for the male than in other mammals, and also makes attempts to sexually coerce (physically force sexual activity on) females futile. Joan Roughgarden, an ecologist and evolutionary biologist, said that because the hyena's clitoris is higher on the belly than the vagina in most mammals, the male hyena "must slide his rear under the female when mating so that his penis lines up with [her clitoris]". In an action similar to pushing up a shirtsleeve, the "female retracts the [pseudo-penis] on itself, and creates an opening into which the male inserts his own penis". The male must practice this act, which can take a couple of months to successfully perform.

When young women start out in porn, producers don't send them off for a routine labiaplasty." Although female genital mutilation – the practice of cutting off a woman's labia and sometimes clitoris, and in some cases creating a seal across her entire vulva – is illegal across the Western world, Simone Davis, a professor and gender theorist at Mount Holyoke College in Massachusetts, argues that "when you really look carefully at the language used in some of those laws, they would also make illegal the labiaplasties that are being done by plastic surgeons in the U.S." The World Health Organization (WHO) defines female genital mutilation as "all procedures that involve partial or total removal of the external female genitalia, or other injury to the female genital organs for non-medical reasons." The WHO writes that the term is not generally applied to elective procedures such as labiaplasty. The American College of Obstetricians and Gynecologists (ACOG) published an opinion in the September 2007 issue of Obstetrics & Gynecology that several "vaginal rejuvenation" procedures were not medically indicated, and that there was no documentation of their safety and effectiveness. ACOG argued that it was deceptive to give the impression that the procedures were accepted and routine surgical practices. It recommended that women seeking such surgeries must be given the available surgical-safety statistics, and warned of the potential risks of infection, altered sensation caused by damaged nerves, dyspareunia (painful sexual intercourse), tissue adhesions, and painful scarring.
==== 2005 Tbilisi grenade attack ==== On May 10, 2005, while President Bush was giving a speech in Freedom Square, Vladimir Arutyunian, a native Georgian who was born to a family of ethnic Armenians, threw a live Soviet-made RGD-5 hand grenade toward the podium. It landed in the crowd about 61 feet (19 m) from the podium after hitting a girl, but it did not detonate because a red tartan handkerchief was wrapped tightly around it, preventing the safety lever from detaching. Georgian president Mikheil Saakashvili was seated nearby. After escaping that day, Arutyunian was arrested in July 2005. During his arrest, he killed an Interior Ministry agent. He was convicted in January 2006 and given a life sentence.

Working at the Royal Society in the 1660s, the physician Richard Lower began examining the effects of changes in blood volume on circulatory function and developed methods for cross-circulatory study in animals, obviating clotting by closed arteriovenous connections. The new instruments he was able to devise enabled him to perform the first reliably documented successful transfusion of blood in front of his distinguished colleagues from the Royal Society. According to Lower's account, "...towards the end of February 1665 [I] selected one dog of medium size, opened its jugular vein, and drew off blood, until its strength was nearly gone. Then, to make up for the great loss of this dog by the blood of a second, I introduced blood from the cervical artery of a fairly large mastiff, which had been fastened alongside the first, until this latter animal showed ... it was overfilled ... by the inflowing blood." After he "sewed up the jugular veins", the animal recovered "with no sign of discomfort or of displeasure". Lower had performed the first blood transfusion between animals. He was then "requested by the Honorable [Robert] Boyle ... to acquaint the Royal Society with the procedure for the whole experiment", which he did in December 1665 in the Society's Philosophical Transactions. The first blood transfusion from animal to human was administered by Jean-Baptiste Denys, eminent physician to King Louis XIV of France, on June 15, 1667. He transfused the blood of a sheep into a 15-year-old boy, who survived the transfusion.

== Function == SLC1A2 / EAAT2 is a member of a family of the solute carrier family of proteins. The membrane-bound protein is the principal transporter that clears the excitatory neurotransmitter glutamate from the extracellular space at synapses in the central nervous system. Glutamate clearance is necessary for proper synaptic activation and to prevent neuronal damage from excessive activation of glutamate receptors. EAAT2 is responsible for over 90% of glutamate reuptake within the brain.

They have also joined GroupRaise, a platform where non-profits can book restaurant fundraisers in their locations. On a national level, Outback partners with Heineken USA and their Heineken with a Heart program to raise funds for various organizations in these communities.
In the Roman Catholic Church, the full-fingered gloves traditionally worn by the pope or other bishops are also known as gauntlets or episcopal gloves, though their use has largely been relaxed since Paul VI.
=== Views on apartheid === In 1966, Player espoused support for the apartheid policies of Hendrik Verwoerd in his book Grand Slam Golf, stating: "I must say now, and clearly, that I am of the South Africa of Verwoerd and apartheid ... a nation which ... is the product of its instinct and ability to maintain civilised values and standards amongst the alien barbarians. The African may well believe in witchcraft and primitive magic, practise ritual murder and polygamy; his wealth is in cattle". Activists publicly demonstrated against Player's espousal of apartheid, including protesting against Player at the 1969 PGA Championship. Australian activists also strongly protested against Player. In 1971 there were several threats to protest against Player at tournaments though they never came to fruition. In October 1974, Australian activists screamed at Player, "Go home, racist!", as he was lining up a putt on the 72nd hole in a tournament he had a chance to win. In a 1987 interview with The Los Angeles Times, Player disavowed the system of apartheid, stating, "We have a terrible system in apartheid ... it's almost a cancerous disease. I'm happy to say it's being eliminated. [...] We've got to get rid of this apartheid." In an interview with Graham Bensinger, Player discussed his early support for apartheid stating that the South African Government had "pulled the wool over our eyes" and that the people were "brainwashed" into supporting these policies.

It is a synthetic peptide built from fifteen amino acids, with a mass of roughly 1419 daltons. The sequence is reported to match a fragment of a protein present in human gastric juice. It is not a naturally circulating hormone.
It is normally supplied as a lyophilized powder in a sealed vial. The powder dissolves readily in water, and stock solutions are typically prepared shortly before use. Cold storage is standard laboratory practice.
The letters are generally read as shorthand for body protection compound. That label comes from the original research context rather than from formal nomenclature. No standardized nonproprietary name exists for the peptide.
The peptide is synthetic, but its sequence matches a segment of a protein present in human gastric juice. It does not occur as a free fifteen-residue peptide in the body.
