Sialic acids are a diverse family of nine-carbon sugars that play crucial roles in biological systems, particularly in cellular recognition and signaling. They are commonly found at the terminal positions of glycan chains on glycoproteins and glycolipids, forming what are known as sialoglycoconjugates. These structures are vital for various physiological processes, including cell-cell interactions, immune responses, and pathogen recognition. In the context of health, sialic acids contribute to the stability and functionality of cells, influencing processes like inflammation and tumor progression. In disease, alterations in sialic acid expression can be indicative of pathological states, such as cancer or infectious diseases, where pathogens often exploit these sugars to evade immune detection. The study of sialic acids and their conjugates thus provides insights into their ultimate roles in both maintaining health and contributing to disease, making them important targets for therapeutic interventions and diagnostics. Delving into their biosynthesis and signaling pathways can enhance our understanding of various health conditions and guide the development of novel strategies to combat diseases linked to sialic acid dysregulation.
