Mucopolysaccharides were isolated from both human and cow colostrums. Each of the fractionated mucopolysaccharides was considered to be homogeneous from behaviors in chromatography, electrophoresis and sedimentation pattern. The fractions isolated from human colostrum were found to contain 51.0_??_78.3% carbohydrates consisting of D-galactose, 2-amino-2-deoxy-D-glucose, N-acetylneuraminic acid, L-fucose and D-glucose, and 31.6_??_11.0% peptides consisting of 16 kinds of amino acids. The sedimentation constants, s20 w, of these fractions were in the range of 0.75 to 1.73 S. The fraction isolated from cow colostrum was found to contain 19.3% carbohydrates consisting of D-galactose, 2-amino-2-deoxy-D-glucose and N-acetylneuraminic acid, and 65.2% peptides or proteins consisting of 18 kinds of amino acids. The sedimentation constant, s20 w, of the fraction was 3.68 S.
