ES921000: CMP-N-acetylneuraminic acidCMP Sialic acid, short for Cytidine Monophosphate Sialic Acid, is a nucleotide sugar that plays a crucial role as an activated form of sialic acid, which is essential for the biosynthesis of glycoproteins and glycolipids in cells. CMP Sialic acid is used as a donor substrate in enzymatic reactions that transfer sialic acid to the growing glycan chains of glycoproteins and glycolipids. This process is catalyzed by a group of enzymes known as
