Sialic acid function
WebIn healthy cells sialic acids play many important roles, including controlling communications between cells and the development of many tissues and organs, including those in the nervous and immune systems. All vertebrate animals, and even some plants and microbes, have sialic acids on their cells, but the collection of different modified forms ... 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 charge on cell membranes. This creates repulsion between cells … 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 … 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 phosphate and phosphoenolpyruvate give rise to sialic acid. Later on, … See more Sialic acids are related to several different diseases observed in humans. Sialic acid deficiency with mutations in the NANS gene Biallelic recessive mutations in the sialic acid synthesis gene, N-acetyl-neuraminic acid synthase … 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 acids are found at all cell surfaces of vertebrates and some invertebrates, and also at certain bacteria that interact with vertebrates. Many viruses such as the Ad26 serotype of adenoviruses (Adenoviridae), rotaviruses ( 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
