N-Acetylmannosamine, manufactured in bulk quantities suitable for large scale cell culture or chemical synthesis, is a ubiquitous but rare monosaccharide involved in a range of metabolic processes. ManNAc is used as a precursor in the chemical or enzymatic synthesis of the neuraminic acids found in glycolipids and glycoproteins. In biological systems it is the precursor compound for the biosynthesis of the sialic acids especially N-acetylneuraminic acid (Neu5Ac, NANA). For this reason N-acetylmannosamine is of keen interest to scientists around the world. Dextra's N-acetylmannosamine is top grade material suitable for all purposes, biological or synthetic.
