N-acetyl-D-mannosamine

Description

N-acetyl-D-mannosamine is a naturally occurring monosaccharide belonging to the chemical class of amino sugars. Its chemical structure features an acetyl group attached to the hydroxyl group of D-mannosamine, contributing to its role as a critical precursor in the biosynthesis of sialic acids. N-acetyl-D-mannosamine can be derived from UDP-GlcNAc through epimerization or obtained from exogenous sources, including various ManNAc derivatives (PMID:41044357 ). This metabolite has garnered attention for its pharmacokinetics, demonstrating absolute bioavailability when administered intravenously in humans (PMID:40968480 ). Additionally, N-acetyl-D-mannosamine monohydrate is being explored for its therapeutic potential in treating GNE myopathy, a rare genetic muscle disorder (PMID:40968480 ). Research has indicated that supplementation with N-acetyl-D-mannosamine can effectively lower levels of Man5 without negatively impacting antibody production or other important quality metrics, although the underlying mechanisms of this effect remain to be fully elucidated (PMID:40963238 ). Overall, N-acetyl-D-mannosamine plays a significant role in various biochemical pathways, particularly those related to glycosylation and cellular interactions.
