1.1. Structure BPC-157 is the term used to refer to a pentadecapeptide, a protein with 15 amino acids. BPC is an acronym for ‘Body Protection Compounds’ and refers to “peptides comprising 8-15 amino acids residues with a molecular weight of 900-1,600 daltons” according to the patent for BPC-157,although another study claims that BPC refers to a gastroprotective protein used to isolate BPC-157. This particular sequence does not share homology with other known gastric peptides, with at least one study noting that this sequence did not register in the Protein BLAST database (as of 2016. There are a few studies in which this peptide is also referred to as PL 14736, PL-10, and Beocin This entry will use the acronym BPC-157 exclusively.
BPC-157 is derived from the protein Thymosin beta 4, also known as TB-500.
BPC-157 is a peptide consisting of 15 amino acids. While they are ‘natural’ compounds, this particular sequence is not known to occur in nature and is derived from another protein.
