title: Heterogeneity in the carbohydrate moiety of the gamma-chain of bovine fibrinogen.
abstract: Two glycopeptides with identical amino acid sequence and carbohydrate composition, but of different sialic acid content were isolated from a combined tryptic-chymotryptic hydrolysate of bovine fibrinogen. Glycopeptide 1 contained two moles, glycopeptide 2 one mole of sialic acid. Both of them may have been derived from the gamma-polypeptide chain according to their amino acid sequence: Gln-Val-Glu-Asn-Lys.
