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.
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 fifteen-amino-acid peptide whose sequence is GEPPPGKPADDAGLV. Its name derives from the phrase body protection compound, a term applied to a protein fraction originally detected in human gastric juice. The short peptide is not that full protein; it corresponds to a stable fragment of the larger molecule. Researchers frequently describe it as a pentadecapeptide because it contains exactly fifteen residues. Its neutral molecular mass is approximately 1419 daltons.
The sequence places several glycine and proline residues near the middle, which may influence how the chain folds in solution. The peptide is linear rather than cyclic, and it carries no disulfide bridges. Commercial material is commonly supplied as the acetate salt, although the free base and other counterion forms also appear. Because the term BPC-157 refers to a specific sequence, samples with slight sequence variants are chemically different substances. Published work generally treats the fifteen-residue sequence as the defining structure.
Physical descriptions in supplier documents and papers usually list the compound as a white to off-white powder. It dissolves readily in water and in common aqueous buffers, and solutions are often prepared fresh before an experiment. Molecular mass near 1419 daltons helps verify identity during mass spectrometry. The powder is somewhat hygroscopic, so moisture exposure can alter the measured mass of a sample. Purity is typically reported as a percentage from chromatographic analysis.

BPC-157 is a synthetic peptide composed of fifteen amino acid residues, with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. Its name derives from body protection compound, a term used for a protein fraction identified in human gastric juice. Researchers in Zagreb first reported the pentadecapeptide in the early 1990s and described it as a stable fragment of that larger protein. The compound is also catalogued as PL 14736 and, in some commercial contexts, as bepecin. Its molecular formula is C62H98N16O22 and its monoisotopic mass is approximately 1419 daltons.
Most published work on BPC-157 consists of preclinical studies, including rodent models of tissue injury, gastrointestinal lesions, and vascular or tendon damage, together with in vitro cell assays. Reviews frequently note that the mechanisms proposed in these papers remain incompletely characterised and that findings have not been confirmed in large randomised human trials. The compound is widely sold as a research chemical rather than a licensed medicine, and labels commonly carry a statement that it is not for human use. Whether any of the reported animal effects translate to humans is an open question rather than an established result.
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.
Most published findings come from rodent experiments using induced injury or surgical models. Human reports remain scarce and are largely observational, which limits how much can be stated with confidence. Questions about absorption, distribution, metabolism, and clearance in people are still open. Dose translation between species is likewise unresolved. Researchers tend to read the animal literature as a starting point rather than a settled account.
==== Competitive assays ==== Competitive assays are generally used for smaller analytes since smaller analytes have fewer binding sites. The sample first encounters antibodies to the target analyte labelled with a visual tag (colored particles). The test line contains the target analyte fixed to the surface. When the target analyte is absent from the sample, unbound antibody will bind to these fixed analyte molecules, meaning that a visual marker will show. Conversely, when the target analyte is present in the sample, it binds to the antibodies to prevent them binding to the fixed analyte in the test line, and thus no visual marker shows. This differs from sandwich assays in that no band means the analyte is present.
== Therapeutic approaches and pharmacology == Therapeutic approaches for IRAP regulation rely on the development of peptidomimetics and small molecule inhibitors. The most explored classes of inhibitors for IRAP are the catalytic or the allosteric site ones.
Following a Round 22 61-point demolition at the hands of lower-placed Hawthorn, Thompson's job was under immense pressure. After a very public review of the club, it was decided that Thompson should keep his job as senior coach. After a shaky start to the 2007 season that led many supporters to believe that nothing had changed from the 2006 season, Thompson led Geelong to a massive 15 match winning streak (the biggest in a single season in club history) and a 106-point win against the Kangaroos in the Qualifying Final which is the 5th biggest finals winning margin in AFL/VFL history. The 2007 season then culminated in one of the biggest, if not the best highlight of Thompson's career, in both a coaching and footballer's role. Thompson coached Geelong to win the AFL premiership in the 2007 AFL Grand Final by more than 100 points, which was the highest winning margin in Grand Final history, against Port Adelaide Football Club at the MCG on 29 September. It was the club's first premiership since 1963, the year of Thompson's birth. After the Essendon Football Club decided not to give Thompson's former mentor, Kevin Sheedy, a renewal of contract, there was speculation that Mark Thompson would take up the senior coaching role at Essendon for the 2008 season. However, with trade week quickly approaching, the club instead appointed Matthew Knights to the position. After Geelong's record-breaking win in the grand final, Geelong under Thompson were red hot favourite to repeat their 2007 success in the 2008 season and their form during the year did nothing to change that.

In 2001, a team at the University of Rome La Sapienza conducted a neutralization-reionization mass spectrometry experiment to investigate the structure of free O4 molecules. Their results did not agree with either of the two proposed molecular structures, but they did agree with a complex between two O2 molecules, one in the ground state and the other in a specific excited state. A chain structure is theoretically possible, but attempts at advanced computational analysis found that it rearranged to the D2d structure.

The New South Wales Corps, later known as the 102d Regiment of Foot, and lastly as the 100th Regiment of Foot, was a formation of the British Army organised in 1789 in England to relieve the New South Wales Marine Corps, which had accompanied the First Fleet to New South Wales. In Australia, the New South Wales Corps gained notoriety for its trade in rum and mutinous behaviour. Reconstituted as the 102d Regiment of Foot, it was transferred to Bermuda and Nova Scotia, before taking part in the Chesapeake campaign of the War of 1812. Reconstituted for the second time after the war as the 100th Regiment of Foot, it was disbanded in 1818.
==== Schizophrenia ==== Patients with Schizophrenia also exhibit decreased levels of ChAT, localized to the mesopontine tegment of the brain and the nucleus accumbens, which is believed to correlate with the decreased cognitive functioning experienced by these patients.
Homopolymers are derived from one monomer. These polymers are made from a lactam or amino acid. The synthetic route using lactams (cyclic amides) was developed by Paul Schlack at IG Farben, leading to nylon 6, or polycaprolactam—formed by a ring-opening polymerization. The peptide bond within the caprolactam is broken with the exposed active groups on each side being incorporated into two new bonds as the monomer becomes part of the polymer backbone. The 220 °C (428 °F) melting point of nylon 6 is lower than the 265 °C (509 °F) melting point of nylon 66.
== Philanthropy == The Dunkin' Joy in Childhood Foundation is an independent 501(c)3 charitable organization founded in 2006 to provide the simple joys of childhood to kids battling hunger or illness. The Foundation partners with food banks, children's hospitals, and nonprofit organizations to fund joyful environments and experiences for children across the country. Since its founding, the Foundation has granted more than $70 million to hundreds of national and local charities. Kari Bornhorst McHugh served as Executive Director from March 2017 to August 2021. In December 2018, McHugh launched the Dogs for Joy program, the first initiative of its scale to place full-time specially trained facility dogs in children's hospitals nationwide, backed by more than $2 million in initial grants. As part of the launch, McHugh brought in Cooper Dunkin', a Black Lab/Golden Retriever mix trained by Canine Assistants, who served as the Foundation's Chief Joy Officer and program ambassador, visiting children's hospitals across the country. In 2020, the Foundation launched Joyful Spaces, a program funding the creation and renovation of playgrounds, healing gardens, and play spaces at children's hospitals. Also during the COVID-19 pandemic, the Foundation introduced Hero Recharge, created in partnership with outdoor adventure nonprofit First Descents to support healthcare workers, which received an honorable mention in the Corporate Social Responsibility category of Fast Company's 2021 World Changing Ideas Awards.

It is a synthetic fifteen-amino-acid peptide whose sequence matches part of a protein found in human gastric juice. It is made by chemical synthesis, not purified from tissue. The name derives from an early fragment label, not from a molecular weight.
The sequence corresponds to a segment of a naturally occurring gastric protein, so related sequence material exists in the body. The peptide itself as sold and studied is a laboratory-synthesized product. Whether an identical free peptide circulates naturally is not established.
No major regulatory agency has approved it as a medicine for any indication. It appears in research supply channels and, in some jurisdictions, in compounded preparations. Clinical use therefore sits outside standard approved-product pathways, and regulatory status varies by country.
The letters BPC stand for body protection compound. The number 157 refers to a specific fragment designation from early work on gastric proteins. The full name is a label for a synthetic fifteen-amino-acid peptide rather than a naturally isolated drug.
