31. After the fusion of the late endosome with the lysosome, lysosomal sialidases remove sialic acid residues. 32. It was therefore expected to have an authentic human form of sialic acid and other oligosaccharide residues. 33. Neuraminidases are enzymes that cleave sialic acid groups from glycoproteins and are required for influenza virus replication. 34. Mucins are constituents of one class of glycoproteins : sialic acid -containing glycoproteins, or mucoproteins. 35. These hemagluttinin proteins bind to sialic acid receptors on host cells, which can fall into two categories. 36. Conversely, the sialic acid content of mouse vagina is a measure of the potency of the estrogen. 37. This paper attempted to reveal their components and the presence of sialic acid in the amorphous ground substance. 38. On one side, it has made humans more susceptible to some viruses by decreasing sialic acid diversity. 39. The ancestral SAS gene was found to have both sialic acid synthase and rudimentary ice-binding functionalities. 40. Variety is found in the degree of core fucosylation and in the type of sialic acid and galactose linkage.
