Sialic acid cation binding

Bovine serum albumin has a molecular weight of about 6.6 X 10" and consists of 581 amino acids. The tertiary structure of the protein is controlled by the 17 disulfide linkages, and at pH 7.0 the net charge on the protein is 18. The human plasma protein, ai-acid glycoprotein, contains five carbohydrate units and has a molecular weight of 4.1 x 10". The 14 sialic acid residues in the sugar units are involved in binding various cationic species and are believed to play a role in the chiral selectivity of this protein. [Pg.2160]

The binding of calcium ions by the mucins of rat small intestines probably involves sialic acid and carboxy-groups, which co-operate to produce a contraction or folding of the molecule on binding of the cation. ... [Pg.319]
