Sialic acid can "hide" mannose antigens on the surface of host cells or bacteria from mannose-binding lectin. [citation needed] This prevents activation of complement. Sialic acid in the form of polysialic acid is an unusual posttranslational modification that occurs on the neural cell adhesion molecules (NCAMs). See more Sialic acids are a class of alpha-keto acid sugars with a nine-carbon backbone. The term "sialic acid" (from the Greek for saliva, σίαλον - síalon) was first introduced by Swedish biochemist Gunnar Blix in 1952. The most common … See more Sialic acid is synthesized by glucosamine 6 phosphate and acetyl-CoA through a transferase, resulting in N-acetylglucosamine-6-P. This becomes N-acetylmannosamine-6-P through epimerization, which reacts with phosphoenolpyruvate producing … See more The synthesis and degradation of sialic acid are distributed in different compartments of the cell. The synthesis starts in the cytosol, where N-acetylmannosamine 6 … See more Rat pups supplemented with sialic acid showed improved learning and memory as adults. A relationship between dietary sialic acid supplementation and cognitive function was seen in piglets that had been fed high doses of sialic acid. See more The sialic acid family includes many derivatives of the nine-carbon sugar neuraminic acid, but these acids rarely appear free in nature. Normally they can be found as components of oligosaccharide chains of mucins, glycoproteins See more Sialic acid containing glycoproteins (sialoglycoproteins) bind selectin in humans and other organisms. Metastatic cancer cells often express a high density of sialic acid-rich glycoproteins. This overexpression of sialic acid on surfaces creates a negative … See more Sialic acids are found at all cell surfaces of vertebrates and some invertebrates, and also at certain bacteria that interact with vertebrates.
