Sr-(Methionyl R-Mussel Polypeptide-1 R-Mussel Oligopeptide-1 R-Mussel Polypeptide-1 Leucine)
A cosmetic ingredient used as antioxidant, hair conditioning, humectant in skincare, haircare, and personal-care products sold in the European Union.
What is it?
sr-(Methionyl r-Mussel Polypeptide-1 r-Mussel Oligopeptide-1 r-Mussel Polypeptide-1 Leucine) is a single chain recombinant peptide produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the genes from r-Mussel Polypeptide-1, r-Mussel Oligopeptide-1, and Leucine with the initiation code for methionine. The fusion peptide contains 162 amino acids which may contain disulfide bonds and/or glycosylation and consists of the proper sequence from the 20 standard amino acids.
