Sialic acid function
WebMar 26, 2024 · The introduction of unnatural sialic acids with different functionalities into surface glycans enables the study of the broad biological functions of these sugars and presents a therapeutic option to intervene with pathological processes involving sialic acids. Multiple chemically modified sialic acid analogs can be directly utilized by cells ... WebSep 21, 2024 · However, the masking functions of sialic acid residues are very important in cell regulation. Masking can have a direct or indirect protective role, depending on whether the sialic acid portion directly covers the antigenic carbohydrate residue, or whether it is a sialic acid in an adjacent glycoconjugate that masks the antigenic portion.

WebIn nature, these monosaccharides occur either in a 3-deoxy form (referred to as “sialic acids”) or in a 3,9-dideoxy “sialic-acid-like”form.The former sialic acids are most common in the deuterostome lineage,including vertebrates,and mimicked by some of their pathogens. The latter sialic-acid-like molecules are found in bacteria and archaea.
