Abstract
Sialic acids (Sias) are monosaccharides composed of nine carbons and are mostly present on the cell surface of vertebrates. Among them, N-acetyl neuraminic acid (Neu5Ac) and N-glycolyl neuraminic acid (Neu5Gc) are the most abundant in mammals. These sugars are involved in several essential processes in human development, for example, making these molecules suitable for carrying informatio…
