CMP-β-D-N-Acetlylneuraminic acid (CMP-Neu5Ac) is a nucleotide sugar and the donor substrate for eukaryotic and prokaryotic sialyltransferases. Furthermore CMP-Neu5Ac is the essential substrate for sialyltransferases (SiaTs) in the synthesis of glycoconjugates. References: Frohnmeyer, H. and Elling, L., Carbohydr.
