Characterization of molecular species of collagen in scallop mantle

Pepsin-solubilized collagen (SMPC) extracted from scallop mantle was first subjected to amino acid analysis and molecular weight determination. The SMPC was rich in hydroxylysine. After salting out, the SMPC showed two different profiles in molecules, amino acids and peptide maps. The two different...

Description
Summary:Pepsin-solubilized collagen (SMPC) extracted from scallop mantle was first subjected to amino acid analysis and molecular weight determination. The SMPC was rich in hydroxylysine. After salting out, the SMPC showed two different profiles in molecules, amino acids and peptide maps. The two different collagen molecules had different uronic acid contents and gel-forming abilities. SMPC may be applicable to a variety of usage, including functional foods.
