The Chemical Structure of Glycolipids of Bovine Milk

Abstract

Experiments were executed to elucidate the chemical structure of ceramide monohexoside (CMH) and ceramide dihexoside (CDH) isolated from cow's milk, especially with regard to the nature of the sugar moiety of the molecules. The results have shown that the structure of CMH and CDH in bovine milk is β-glucosyl-(1→1)-N-acyl-sphingosine, namely ceramide glucoside, and β-galactosyl-(1→4)-β-glucosyl-(1→1)-N-acyl-sphingosine, namely ceramide lactoside, respectively.
