Isolation of a Glycine-Carbohydrate Residue from Muscle Collagen


ONE of a group of related, macromolecular substances composed of an amino-acid linked to a polysaccharide has been isolated and partially characterized. This group of substances, obtained by means of proteolysis of muscle collagen by carboxypeptidase and subsequent electrophoresis of the non-dialysable fraction, suggests the existence of a polysaccharide residue linked to the C-terminal amino-acid.
