This is a working overview of gastric juice protein, written for readers who want more than a one-paragraph summary but less than a textbook.
This page was last updated on 2026-04-05 and is reviewed periodically as new material appears.
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 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.
Common synonyms in catalogs include pentadecapeptide BPC 157, BPC157, and the full sequence name. A CAS registry number in the 137525-51-0 range is frequently listed, though the assignment should be verified against the supplier certificate of analysis. The name itself is not a pharmacopoeial designation, and there is no standardized international nonproprietary name. Distinguishing genuine material from related fragments generally requires mass spectrometry, since several truncated sequences share similar chromatographic behavior.
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.
| Property | Value | Notes |
|---|---|---|
| Molecular formula | C62H98N16O22 | Approximate, for sequence GEPPPGKPADDAGLV |
| Molecular mass | ~1419 Da | Neutral form |
| Appearance | White to off-white powder | Lyophilized solid |
| Solubility | Soluble in water | Also soluble in aqueous buffers |
| Typical storage | -20 C | Dry powder, protected from moisture |
Published storage guidance follows general peptide practice rather than product-specific studies. The dry powder is typically kept at minus 20 degrees Celsius, away from light and moisture. Once reconstituted, solutions are generally refrigerated and used over days to weeks, because the aqueous environment slowly promotes hydrolysis and oxidation. Long-term data on degradation rates or breakdown products are sparse. Stated shelf lives from different producers vary widely, reflecting the absence of a shared reference standard.
BPC-157 is a synthetic peptide built from fifteen amino acid residues. Its sequence comes from a larger protein fragment that researchers isolated from human gastric juice and described as a body protection compound. The fragment contains glycine, glutamic acid, five prolines, lysine, alanine, two aspartic acids, leucine, and valine. The number 157 in the name refers to the position of the stretch within the parent protein. Material used in laboratories is manufactured rather than extracted from stomach fluid.
The molecule carries 15 residues, a molar mass near 1419.5 g/mol, and the formula C62H98N16O22. Its structure features a proline-rich central region, a pair of adjacent aspartic acid residues, and no cysteine. The absence of cysteine means no disulfide bonds can form, which simplifies refolding and reconstitution. Suppliers usually ship the material as a freeze-dried powder that appears white to off-white. It dissolves readily in water and in saline solutions.
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 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.
Within the research literature, the peptide is discussed through several provisional mechanisms, including cytoprotection, modulation of growth factor signaling, and interaction with the nitric oxide system. None of these mechanisms is fully characterized, and no single pathway is universally accepted. Review articles typically note the gap between consistent animal findings and sparse human evidence. The compound is classified as a research chemical rather than an approved pharmaceutical, which shapes how studies are designed, funded, and reported.
BPC-157 is a synthetic pentadecapeptide with the sequence GEPPPGKPADDAGLV, corresponding to a partial fragment of a larger protein detected in human gastric juice. The name derives from the parent protein designation BPC, an abbreviation of body protection compound, with 157 acting as a fraction or batch identifier used by the original investigators. Its molecular weight is approximately 1419 daltons, and the chain contains no unusual residues or disulfide bridges. In the literature it is described as a short, water-soluble fragment rather than a complete natural protein.
In its native range, mashua is mainly cultivated for its edible tubers. Still, it has ornamental value in the temperate zone because of its trailing habit and showy, bi-colored tubular flowers, which appear in summer and autumn. The sepals are orange-red, while the petals are bright yellow. In areas prone to frost, some protection is required in winter. The cultivar T. tuberosum var. lineamaculatum 'Ken Aslet' has gained the Royal Horticultural Society's Award of Garden Merit.
Starfish are sometimes eaten in China, Japan, and Palau. Some species, such as the crown-of-thorns starfish, are toxic. Georg Eberhard Rumpf found few starfish being used for food in the Indonesian archipelago, other than as bait in fish traps, but on the island of "Huamobel" [sic], the people cut them up, squeeze out the "black blood" and cook them with sour tamarind leaves; after resting the pieces for a day or two, they remove the outer skin and cook them in coconut milk.
TCEP (tris(2-carboxyethyl)phosphine) is a reducing agent frequently used in biochemistry and molecular biology applications. It is often prepared and used as a hydrochloride salt (TCEP-HCl) with a molecular weight of 286.65 gram/mol. It is soluble in water and available as a stabilized solution at neutral pH and immobilized onto an agarose support to facilitate removal of the reducing agent.

=== Pyrimidine catabolism === Cytosine and uracil are converted into beta-alanine, which is further processed into malonyl-CoA, a key precursor for fatty acid synthesis and other metabolic pathways. Thymine, on the other hand, is converted into β-aminoisobutyric acid, which is then used to form methylmalonyl-CoA. The remaining carbon skeletons, such as acetyl-CoA and succinyl-CoA, can be further oxidized in the citric acid cycle. Pyrimidine degradation ultimately results in the formation of ammonium, water, and carbon dioxide. The ammonium can then enter the urea cycle, which takes place in both the cytosol and mitochondria of cells. Pyrimidine bases can also be salvaged. For example, the uracil base can be combined with ribose-1-phosphate to form uridine monophosphate (UMP). A similar reaction occurs with thymine and deoxyribose-1-phosphate. Deficiencies in enzymes involved in pyrimidine catabolism can lead to diseases such as Dihydropyrimidine dehydrogenase deficiency, which causes neurological impairments.
=== Expression of VIP === VIP is produced in the neurons in the central and peripheral nervous systems. VIP is mainly localized in the myenteric and submucosal neurons and nerve terminals in the GI tract. Endogenous VIP is released by numerous stimuli such as acetylcholine (ACh), ATP, serotonin (5-HT), substance P (SP), GLP-2 from at least two populations of VIP-positive nerves: cholinergic and non-cholinergic VIP-releasing nerves. In guinea pig small intestine, most VIP-positive nerves in the mucosa and submucosa are non-cholinergic secretomotor neurons and well colocalized with neuronal nitric oxide synthase (nNOS) in human colonic circular muscles. VIP is also expressed in immune cells, such as activated T cells and therefore present in lymphoid tissues including Peyer's patches, the spleen, and lymph nodes, in addition to the VIP-ergic innervation in lymphoid tissues. Beside the neuronal source, VIP is also expressed and released from endocrine organs - Heart, Thyroid, Kidney and GI tracts.
The thyroid gland received its modern name in the 1600s, when the anatomist Thomas Wharton likened its shape to that of an Ancient Greek shield or thyos. However, the existence of the gland, and of the diseases associated with it, was known long before then.
Two days later, five Italian fighters attacked a group of grounded Rhodesian aircraft at Agordat in western Eritrea, and wrecked two Hardys and two Lysanders. Platt's advance into Eritrea was checked during the seven-week Battle of Keren (February–April 1941), during which No. 237 Squadron observed Italian positions and took part in bombing raids. After the Italians retreated and surrendered, the Rhodesian squadron moved forward to Asmara on 6 April, whence it embarked on bombing sorties on the port of Massawa. The same day, the Italian garrison in the Abyssinian capital Addis Ababa surrendered to the 11th (East Africa) Division, including many Rhodesians. During the Battle of Amba Alagi, Platt and Cunningham's forces converged and surrounded the remainder of the Italians, who were commanded by the Duke of Aosta at the mountainous stronghold of Amba Alagi. The viceroy surrendered on 18 May 1941, effectively ending the war in East Africa. No. 237 Squadron and the Rhodesian Anti-Tank Battery thereupon moved up to Egypt to join the war in the Western Desert. Some Italian garrisons continued to fight—the last surrendered only following the Battle of Gondar in November 1941. Until this time the partly Rhodesian-commanded Nigeria and Gold Coast Regiments remained in Abyssinia, patrolling and rounding up scattered Italian units. Around 250 officers and 1,000 other ranks from Southern Rhodesia remained in Kenya until mid-1943.
== Epidemiology == Leiomyosarcomas are rare. Sarcomas combined account for less than 1% of cancer diagnoses, and leiomyosarcoma accounts for around 10% of sarcoma diagnoses. Around 63% of uterine sarcomas, 20% of abdominal sarcomas, and 15% of sarcomas of the arms and legs are leiomyosarcomas. Non-uterine leiomyosarcoma is around 40% more common in women than in men. The disease generally affects older adults with the average person diagnosed around age 60. Uterine leiomyosarcoma most commonly impacts women in perimenopause, with an average age of diagnosis at 57.

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.
No. The gastric protein is larger, while BPC-157 is a short fragment sequence. The peptide is produced synthetically for research use. The relationship is one of sequence origin, not chemical identity.
It is most often supplied as a lyophilized powder, frequently as the acetate salt. The powder is reconstituted with water or a buffer before use. Free-base and other salt forms also exist but are less common in catalogs.
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.
