Frequently Asked Questions

What is N-acetylneuraminic acid also known as?

N-Acetylneuraminic acid (CAS 131-48-6) is also known as sialic acid, Neu5Ac, or NANA. It is the principal sialic acid, a nine-carbon amino sugar acid that occurs in polysaccharides, glycoproteins, and glycolipids.

Is NANA the same as sialic acid?

Yes. NANA (N-acetylneuraminic acid, CAS 131-48-6, Neu5Ac) is the principal member of the sialic acid family, so it is commonly referred to simply as sialic acid. It is supplied as a glycoscience reference compound and specialty ingredient.

Is N-acetylneuraminic acid an amino sugar?

Yes. N-Acetylneuraminic acid is a nine-carbon amino sugar acid (formula C11H19NO9), the principal sialic acid found in glycoproteins and glycolipids. It is used as a biochemical building block and reference compound in glycoscience.
