• The tetrapeptide originating from a peptide synergist consisting of 21 amino acid residues (peptide C-1) was found to increase the antioxidative activity of α-tocopherol (Toc) and sodium ascorbate (AsA). Peptide C-1, which had been previously isolated from bovine serum albumin hydrolysates, was again hydrolyzed with a lysyl endopeptidase to give three peptide fragments. Each fragment was tested for its synergistic effect with Toc and AsA, and only one fragment had a potent synergism comparable to the original peptide, C-1. The structure of the active fragment was confirmed as the tetrapeptide, Asp-Thr-His-Lys, by amino acid analysis and sequence determination. In addition, peptide C-1 and its active fragment corresponded to residues 1 to 21 and 1 to 4 of BSA, respectively.
