In sialic acid storage disorders, 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 Mar 8, 2021 Sialic acid-Dependent Binding and Viral Entry of SARS-CoV-2. Linh Nguyen, Kelli A. McCord, Duong T. Bui, Kim M. Bouwman, Elena N. Kitova, Sep 24, 2020 N-acetylneuraminic acid (Neu5Ac, sialic acid) is a negatively charged monosaccharide, and the predominant form of sialic acid in human cells AdvanceBio Sialic Acid Profiling and Quantitation kits provide workflows for robust and rapid preparation of samples for sialic acid quantitation and profiling. The sialic acids which are bound to sugar chain in glycoproteins or glycolipids can also be measured after pre-treatment with sialidases or acid hydrolysis.
total sialic acid, 'lipid-bound'and 'proteinbound'sialic acid have all been proposed as tumour markers; but the usefulness of any of these tests is severely limited by changes due to accompanying inflammatory processes.

Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,3- or alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface.

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]
Sialic acids are released from glycoproteins by mild acid hydrolysis using conditions that preserve the N-acetyl, N -glycolyl and O -acetylation.

ABSTRACT. Sialic acids decorate the surfaces of most mammalian cells and are used by many viruses as attachment receptors. In contrast to other mammals, This sugar is provided for use as an inhibitor of lectin-conjugate binding or for eluting glycoproteins or other glycoconjugates from columns of agarose lectins. Oct 29, 2015 Sialic acids are based on 5-amino-3,5-dideoxy-d-glycero-d-galacto-nonulosonic acid (1) (Figure 1).
The chemical structure of sialic acid, which features an anomeric center with carboxyl and methylene substituents, poses a challenge for synthesis of the α-glycoside, thus impeding biological and therapeutic studies on sialic acid–containing glycans. Sialic acid storage disease is an inherited disorder that primarily affects the nervous system. People with sialic acid storage disease have signs and symptoms that may vary widely in severity. This disorder is generally classified into one of three forms: infantile free sialic acid storage disease, Salla disease, and intermediate severe Salla disease. 2020-03-17 · Sialic acids are a heterogeneous group of monosaccharides that play key roles in human glycobiology.
Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Binds equally to alpha-2,3-linked and alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface. Sialic acid, a 9-carbon sugar molecule with a strong negative charge (also known as N-acetylneuraminic acid), occurs in large amounts as a component of human milk oligosaccharides (8, 9). Sialic acid is also the terminal functional residue of brain gangliosides and glycoproteins, such as the neural cell adhesion molecule (NCAM). Sialic acids (Sias) are typically attached to the outer end of cell surface and secreted glycoconjugates of higher animals (Schauer, 1982; Varki, 1992; Kelm and Schauer, 1997).
