• Unveiling the Multidimensional Utility of N-Acetylneuraminic Acid

Abstract

N-acetylneuraminic acid (sialic acid), a fundamental component of cell surface glycans, holds a myriad of physiological roles. Recognized for its terminal position in various glycoconjugates, sialic acid is a cornerstone in the food, cosmetic, and pharmaceutical sectors. This review delves into the physiological roles of sialic acid, its safety and regulatory landscape, and its applications. We also explore the biosynthetic pathways of sialic acid, including enzymatic and microbial methods, and address the challenges and strategies for its industrial-scale production.
