Xaa is a neutral aliphatic amino acid residue, in particular Ala, bAla, Leu, Ile, Gly, Val, Nle or the cation of the salt is an alkali metal or an alkaline earth metal, for instance Na + , K + , Li + , Cs + , Ca 2+ , or another metal, such as Zn 2+ , or a primary, secondary or tertiary amine or organic compound, such as NH 4 + , triethanolamine + , cyclohexylamine + , 2-AMP + (2-amino-1-propanol) or TRIS + (Tris-(hydroxymethyl)-aminomethan), as long as these cations are physiologically acceptable
Further analysis using Western blotting indicates that BPC-157 may activate the FAK (focal adhesion kinase) and paxillin proteins
Pro Tips A simple way to improve your understanding of peptides is to read primary literature (PubMed) instead of relying on marketing summaries
Three interconnected pathways function as core suppressors of ferroptosis: (1) the GPX4-GSH system (central suppressor), (2) the SLC7A11-cystine import pathway (GSH synthesis), and (3) the AIF family member 2 (AIFM2, also known as FSP1)-NAD(P)Hquinone pathway (parallel protection) 84-87
