2,3,4,6-Tetra-O-acetyl-D-galactopyranose

2,3,4,6-O-四乙酰基-D-半乳糖,

2,3,4,6-Tetra-O-acetyl-D-galactopyranose is a glycoside that has been used as an antigen in immunological studies and to study the role of fatty acids in cancer. This compound is phosphorylated to form 2,3,4,6-tetra-O-phospho-D-galactopyranose and reacts with primary alcohols to form transglycosylation products. 2,3,4,6-Tetra-O-acetylgalactopyranose also reacts with chloride ions to form disaccharides. As a result of these reactions 2,3,4,6-tetraacetylgalactopyranose has shown anticancer activity.
