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 … Visa mer 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 … Visa mer Sialic acids are found at all cell surfaces of vertebrates and some invertebrates, and also at certain bacteria that interact with vertebrates. Visa mer The synthesis and degradation of sialic acid are distributed in different compartments of the cell. The synthesis starts in the cytosol, … Visa mer Sialic acids are related to several different diseases observed in humans. Sialic acid deficiency with mutations in the NANS gene Biallelic recessive … Visa mer The sialic acid family includes many derivatives of the nine-carbon sugar neuraminic acid, but these acids rarely appear free in nature. … Visa mer 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 … Visa mer Rat pups supplemented with sialic acid showed improved learning and memory as adults. A relationship between dietary sialic acid … Visa mer Webb1 nov. 2004 · This work is of particular relevance to large-scale transgenic plant production systems for recombinant human protein therapeutics, which often require complex glycosylation, such as sialylation ...
