'Sialic acid'is the generic namegiven to a family ofcompounds derived from the 9-carbonsugar neuraminic acid. By far the major derivative in human tissues is N-acetylneuraminic acid (NANA). Other sialic acids contain a range of substituents, singly or in combination, in the positions indicated (Fig. 1). Sialic acids are terminal sugar components of

SCHENGRUND published "Biological Roles of Sialic Acids" (Plenum Press). シアル酸 (sialic acid) とは、ノイラミン酸 (neuraminic acid) のアミノ基やヒドロキシ基が置換された物質を総称するファミリー名である。通常糖鎖の非還元末端に存在し、細胞の認識など重要な機能を担っている。 Sialic acids represent a family of sugar molecules with an unusual and highly variable chemical structure that are found mostly in the terminal position of oligosaccharide chains on the surface of Sialic acids have numerous modifications, resulting in a variety of different structures. In 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. To determine how well the used sugar derivatives are incorporated as sialic acid and to quantify absolute sialic acid levels, we used a previously described technique, the DMB labeling reaction.

They are widely distributed in Nature, mainly in vertebrates, but also in higher invertebrates and Rapid progress in the field of sialic acids has made it desirable to collect the new data about these unique sugars and to continue the series of books on this topic. In 1960, A. GOTTSCHALK wrote "The Chemistry and Biology of Sialic Acids and Related Substances" (Cambridge University Press) and in Summary: This gene encodes a serine hydrolase that belongs to the esterase D family. The encoded enzyme is active toward numerous substrates including O-acetylated sialic acids, and it may be involved in the recycling of sialic acids. This gene is used as a genetic marker for retinoblastoma and Wilson's disease. [provided by RefSeq, Feb 2009] 2014-06-15 The sialic acid family includes 43 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 and glycolipids occupying terminal, nonreducing positions of complex carbohydrates on both external and internal membrane areas where they are very exposed and … sialic acids present in biotherapeutic glycoproteins as well as the NISTmAb. This kit uses a new and improved high-throughput workflow for the preparation, separation, and detection of sialic acids labeled with 1,2-diamino-4,5-methylenedioxybenzene (DMB).

Summary: This gene encodes an enzyme which removes 9-O-acetylation modifications from sialic acids. Mutations in this gene are associated with susceptibility to autoimmune disease 6. Multiple transcript variants encoding different isoforms, found either in the cytosol or in the lysosome, have been found for this gene.[provided by RefSeq, Feb 2011]

Nova [online]. 2005, vol.28, n.2, pp.306-316. Many LC-based methods begin with the release of the targeted sialic acids under milder acid hydrolysis conditions (e.g., 2 M acetic acid for 2 hours at 80 °C). The 10 Oct 2019 Modified sialic acid and pathogen interactions.

Sialic acids play important roles in many physiological and pathological processes via carbohydrate-protein interactions, including cell–cell communication, bacterial and viral infections. 432 The Sialic Acids.

Sialic acids are a group of negatively charged nine-carbon monosaccharides, which are mostly found as the terminal residue of glycoconjugates in eukaryotes or pathogenic bacteria where they play important roles in mediating cellular recognition, adhesion processes, and protecting the underlying tissue.

sialic acid conjugates, i.e. derivatives of sialic acid, 3’-sialyllactose and N-acyl modified sialic acids, and their multivalent counterparts on human serum albumine (HSA) have been developed. Evaluation of these conjugates in cell binding and cell infectivity assays revealed that they are effective as inhibitors. Moreover the results

The sialic acids, a family of acylated derivatives of neuraminic acid (2-keto-5-amino-3,5-dideoxy-n-nonulosonic acid), are widely distributed in nature, generally as components of the oligosac- Salicylic acid (from Latin salix, "willow tree") is a lipophilic monohydroxybenzoic acid, a type of phenolic acid, and a beta hydroxy acid (BHA). This colorless crystalline organic acid is widely used in organic synthesis, and functions as a plant hormone.
