gastric juice is one of those subjects where the details matter more than the headlines. This page pulls together the background, the mechanisms, and the practical points readers ask about most.
Last reviewed on 2026-04-15. Where a claim depends on a specific study, the study is described rather than over-claimed.
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.
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.
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.
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.

BPC-157 is normally distributed as a lyophilised powder that ranges from white to off-white in appearance. The peptide dissolves readily in water, normal saline, and common aqueous buffers, and it is poorly soluble in nonpolar solvents such as hexane or vegetable oils. Lyophilised vials take up moisture if left open, which changes the mass of powder in the container and complicates any later weighing. Because the material is handled in small quantities, static and adhesion to glass or plastic can also cause noticeable losses during transfer.
The main chemical liabilities of this sequence are peptide-bond hydrolysis and possible aspartate-related reactions, since the peptide contains aspartic acid residues but no cysteine, methionine, or tryptophan. Absence of those three residues removes the most common oxidation and disulfide pathways from consideration. Studies of related peptides indicate that aspartate isomerisation and aspartimide formation occur most readily at Asp-Gly and Asp-Ala positions, and open questions remain about how quickly those reactions proceed under ordinary laboratory conditions. Storage guidance typically emphasises cool, dry, dark conditions to slow hydrolysis.
Identity and purity are usually assessed with reversed-phase high-performance liquid chromatography, often paired with mass spectrometry using electrospray or MALDI ionisation. Amino acid analysis and peptide mapping by enzymatic digestion provide additional sequence-level confirmation. Purity is commonly reported as an area percentage from a chromatographic trace, and water content can be measured by Karl Fischer titration. Reported masses may differ by tens of daltons between sources because preparations can contain acetate or trifluoroacetate counterions, and such differences are not by themselves evidence of a different peptide.
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.
Lyophilized peptide powder is generally stored at minus twenty degrees Celsius or lower and kept away from light and moisture. Under these conditions degradation is slow, and sealed vials remain stable for extended periods. Once dissolved, the material is less stable, particularly in aqueous buffers near neutral pH, where hydrolysis and oxidation proceed faster. Solutions are usually kept cold and used within days to weeks. Repeated freeze-thaw cycles are avoided because they encourage aggregation.
Identity and purity are established using reversed-phase high-performance liquid chromatography, which separates the peptide from related impurities and yields a percentage purity. Mass spectrometry, typically with electrospray ionization, confirms the molecular mass against the expected value. Amino acid analysis or peptide mapping provides additional sequence confirmation. These methods are complementary, since chromatography measures how much material is present while mass spectrometry verifies what that material is. A certificate of analysis normally reports both.

== Distribution and habitat == Euphorbia caducifolia has a rather limited distribution in the Thar Desert in the northwestern part of the Indian subcontinent, on the boundary between India and Pakistan. This is an area of sandy hills and shifting sand dunes, with clumps of thorny vegetation, low trees, grasses and scrub.

It does not occur in the form that is supplied commercially. Its sequence matches a fragment of a larger gastric protein, and the research material is produced synthetically in a laboratory. The fragment described in the early literature is generally the same synthetic pentadecapeptide.
It marks the position of the sequence inside the original protein. The label traces back to early work fractionating gastric juice and describing a body protection compound. The figure does not refer to molecular weight or to the count of amino acids.
No. The sequence has no cysteine residues, so disulfide bridges cannot form. That feature makes it easier to handle than many small proteins that depend on multiple cysteines for structure.
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.
