Cytidine Monophosphate N Acetylneuraminic Acid, commonly abbreviated as CMP-NANA, is a complex chemical compound with significant biological importance. It serves as a precursor for the synthesis of sialic acid, a vital component in various biological processes. Although CMP-NANA is unique in its structure and function, there are no widely recognized synonyms for this specific compound. However, CMP-NANA is sometimes referred to as Neu5Ac-CMP or N-Acetylneuraminic acid-CMP, indicating its relationship to sialic acid. These terms are used to highlight the presence of acetyl groups in the compound while maintaining its connection to the parent molecule, neuraminic acid.
