Sialic Acid and Cancer

2014
Sialic acids are nine-carbon acidic monosaccharides found in terminal position of glycan chains. The sialylation of cell surface glycoconjugates is frequently altered in cancers, resulting in the expression of sialylated tumor-associated carbohydrate antigens that are specific markers for this disease.

Turnover of Free Sialic Acid, CMP‐Sialic Acid, and Bound Sialic Acid In Rat Brain

Journal of Neurochemistry, 1981
Abstract: Adult male rats were injected intraventricularly with N‐[3H]acetylmannosamine. After different time intervals the rats were killed and free sialic acid, CMP‐sialic acid, lipid‐ and protein‐bound sialic acid were isolated from brain and the specific radioactivities determined. Maximal specific radioactivity was reached after approximately 4 h

Sialic acid activation

Glycobiology, 1991
Cytidine 5'-monophosphosialic acid (CMP-sialic acid) is the activated form of sialic acid which is required for the biosynthesis of sialic acid-containing complex carbohydrates. Its discovery over 30 years ago by the laboratory of Dr Saul Roseman was a landmark in research dealing with the biosynthesis of these compounds.

Sialic Acids in Neurology

2019
Sialic acid (Sia) is involved in many biological activities and commonly occurs as a monosialyl residue at the nonreducing terminal end of glycoconjugates. The loss of activity of UDP-GlcNAc2-epimerase/ManNAc kinase, which is a key enzyme in Sia biosynthesis, is lethal to the embryo, which clearly indicates the importance of Sia in embryogenesis ...
