Some proteolytic digests of chicken egg white ovomucin were fractionated and characterized. It was shown that there are at least three types of carbohydrate side chains in ovomucin; a chain composed of galactose, galactosamine, sialic acid and sulfate in a molar ratio of about 1: 1: 1: 1, a chain composed of galactose and glucosamine in a molar ratio of about 1:1, and a chain composed of mannose and glucosamine in a molar ratio of about 1:1. It was also shown that the carbohydrate side chain composed of galactose, galactosamine, sialic acid and sulfate is linked O-glycosidically to serine or threonine in the protein core of ovomucin.
