Sialic acid function
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.
