May 5, 2009 Avian influenza virus strains preferentially bind to sialic acids attached to galactose via an alpha(2,3) linkage. This is the major sialic acid on

Sialic acids are found widely distributed in animal tissues and to a lesser extent in other species ranging from plants and fungi to yeasts and bacteria, mostly in glycoproteins and gangliosides. It has been shown recently that sialic acid level may be associated with developmental and pathological stages.

Most sialic acids are bonded via the 2, 3, 6 and occasionally 8 hydroxyl groups (number dependent on the carbon to which they are attached), in an α anomeric configuration. Monosaccharide and sialic acid analysis is applicable to all stages of biopharmaceutical development and manufacturing processes including cell line and clone selection, upstream and downstream process development and manufacturing in-process control, batch consistency and release.

: any of a group of reducing amido acids that are essentially carbohydrates and are found especially as components of blood glycoproteins and mucoproteins. Sialic acid is primarily present on biopharmaceuticals linked as alpha2,3 or alpha2,6. SialEXO is a broad acting sialidase mix that will hydrolyze all sialic acid linkages including alpha2,3, alpha2,6, and alpha2,8. 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 are found widely distributed in animal tissues and to a lesser extent in other species ranging from plants and fungi to yeasts and bacteria, mostly in glycoproteins and gangliosides.

Sialic acid is a small chemical that serves as a component of a number of more complex chemical structures in the human body. A disturbance in a gene

sialic (not comparable). Of or pertaining to saliva.

SUMMARY Sialic acids are structurally unique nine-carbon keto sugars occupying the interface between the host and commensal or pathogenic microorganisms. An important function of host sialic acid is to regulate innate immunity, and microbes have evolved various strategies for subverting this process by decorating their surfaces with sialylated oligosaccharides that mimic those of the host.

adj. 1. Of, relating to, or producing saliva.

From the Cambridge Jun 15, 2014 Tumor cells of various origins feature increased expression of sialic acid sugars on membrane glycoproteins and glycolipids and their secretion Nov 1, 2018 The negatively charged sugar sialic acid (Sia) occupies the outermost position in the bulk of cell surface glycans.

This disorder is generally classified into one of three forms: infantile free sialic acid storage disease, Salla disease, and intermediate severe Salla Sialic acid (SA) is normally expressed on the cell membranes and is located at the terminal position of the sugar chains. SA plays an important role for regulation of the innate immunity, function as markers of the cells and can be recognized by a variety of receptors. 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.

"Sialic acid is part of the molecular language that cells use to communicate among themselves," said Ronald L. Schnaar, Ph.D., a senior researcher involved in the work from the Departments of 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).

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. 1–3 Klenk went on to purify sialic acid-containing glycosphingolipids from human brain and recommended the name “ganglioside” for them as a group. 4 Consistent with his structural determination, gangliosides …

Sialic acids are cytoprotectors, mainly localized on the surface of cell membranes with multiple and outstanding cell biological functions. The history of their structural analysis, occurrence, and functions is fascinating and described in this review.
