N-Acetylneuraminic acid (NANA), commonly known as sialic acid, is a key biochemical reagent used in various research applications. This 25mg formulation is often used in glycosylation studies, particularly in investigations of cell surface glycoproteins and glycosaminoglycans. Sialic acid plays a crucial role in cellular interactions, immunity, and pathogen recognition. It is also involved in various enzymatic processes and is used in the synthesis of glycoproteins, glycolipids, and other complex carbohydrates. NANA is widely used in structural biology, enzymology, and biochemical research, helping researchers explore the roles of sialic acid in cellular processes and disease mechanisms.
