Carbohydrate Component in 7S Protein of Soybean Casein Fraction

Abstract

The purified 7S protein from soybean casein fraction contained approximately 4% mannose per protein. Mannose in the protein com-bined tightly with the protein and seemed to make a protein-carbohydrate complex as a glycoprotein. Hexosamine which was con-tained in the 7S protein was about 1.2% per protein.
