This colorless crystalline organic acid is widely used in organic synthesis , and functions as a plant hormone . All forms of free sialic acid storage disease are caused by genetic changes (mutations) in the SLC17A5 gene and are inherited in an autosomal recessive manner. Free sialic acid storage disease can be diagnosed by laboratory tests looking for sialic acid in the urine, imaging studies of the brain, and genetic testing. Sialic acid was first isolated from bovine saliva by Gunnar Blix and concurrently from human brain lipids by Ernst Klenk, who coined the term neuraminic acid for his brain-derived monosaccharide.
Monocyte-derived phagocytes (stained by CD14-PE, shown in red) and UV-B irradiated (90 mJ/cm 2) apoptotic lymphoblasts (stained by CFSE, shown in green) were co-cultured for 24 hours. Sialic acids (Sias) comprise a family of 9-carbon carboxylated sugars. The Sia family consists of nearly 50 members that are derivatives of N-acetylneuraminic acid (Neu5Ac), N-glycolylneuraminic acid (Neu5Gc), and 3-deoxy-d-glycero-d-galacto-non-2-ulopyranosonic acid (deaminoneuraminic acid; 2-keto-3-deoxy-d-glycero-d-galacto-nononic acid; Kdn) (Fig. 1). 1 The diversity of these structures is sialic acid plays an important role in rapid brain growth.

2019-04-01 · Free sialic acid storage disease can be diagnosed by laboratory tests looking for sialic acid in the urine, imaging studies of the brain, and genetic testing. Treatment is based on the symptoms and maintaining quality of life. People with the least severe form of this disease (Salla disease) can live into adulthood. Sialic acids(Sias) comprise a family of 9-carbon carboxylated sugars. Sialic acid is a critical component of the oligosaccharide portion of many glycoproteins. Two varieties of disturbance of sialic acid metabolism may result in neonatal disease with neuronal storage.

A diverse range of sialic acids are found in nature, but the two major sialic acid species found on N- and O-linked glycans contained in biopharmacuticals are N-acetyl-neuraminic acid (Neu5Ac) and N-glycolyl-neuraminic acid (Neu5Gc). 2002-05-15 2014-09-29 In general, sialic acids normally exist as the terminal sugars in the periphery of oligosaccharides via different glycosidic linkages (α2,3, α2,6 α2,8, and α2,9) .Polysialic acid (PSA), a linear homopolymer of sialic acids mainly in α-2,8 and/or α-2,9 linkages, is usually attached to glycoproteins, such as the neural cell adhesion molecule (NCAM) [8,9]. Sialic acids are a diverse family of sugar units with a nine-carbon backbone that are typically found attached to the outermost ends of these chains. Given their location and ubiquitous distribution, sialic acids can mediate or modulate a wide variety of physiological and pathological processes. På svenska. Toggle search The particles are designed to bind sialic acid, a monosaccharide that is highly up-regulated during inflammation, and to stop protein-protein or cell-cell interactions depending on size.

The most common member of this group is N-acetylneuraminic acid found in animals and some prokaryotes. Sialic acids are found widely distributed in animal tissues and related forms are found to a lesser extent in other organisms like in some micro-algae, bacteria and archaea.

N-Acetylneuraminic acid (Neu5Ac or NANA) is the predominant sialic acid found in human cells, and many mammalian cells. Other forms, such as N-Glycolylneuraminic acid , may also occur in cells. This residue is negatively charged at physiological pH and is found in complex glycans on mucins and glycoproteins found at the cell membrane . Located at the outer end of glycans, sialic acids are at the center of numerous molecular interactions at the cell surface. For example, sialic acids influence the biochemical properties and functions of glycoproteins and lipids, mask underlying glycans, mediate cell adhesion and migration and serve as ligands for sialic acid-binding proteins like factor H, selectins and the Siglecs (Schauer Abstract.
