Sialic acid is a generic term for the N- or O-substituted derivatives of neuraminic acid, a monosaccharide with a nine-carbon backbone. It is also the name for the most common member of this group, N-acetylneuraminic acid (Neu5Ac or NANA).

Viruses and sialic acids. Introduction. The first critical step during a viral infection is the binding to specific receptors at the surface of target cells. Several viruses Sialic acids: from the comprehension of their involvement in biological processes to antiinfluenza drug design.

They not only pose a barrier to microorganisms inhabiting or invading an animal mucosal surface Sialic acids play important roles in many physiological processes (e.g., protein folding, neural development, cell-cell interactions) as well as pathological processes (e.g., autoimmunity, cancer Porcine epidemic diarrhea virus (PEDV) and transmissible gastroenteritis virus (TGEV) have been reported to use aminopeptidase N (APN) as a cellular receptor. Recently, the role of APN as a receptor for PEDV has been questioned. In our study, the role of APN in PEDV and TGEV infections was studied in primary porcine enterocytes. After seven days of cultivation, 89% of enterocytes presented 2013-05-24 2007-01-12 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. 20 For this purpose, metabolically engineered cells were incubated with 3 m acetic acid at 80 °C for 90 minutes to detach the sialic acids and lyse the cells (Scheme 1, path B). Examples of how to use “sialic” in a sentence from the Cambridge Dictionary Labs Sialic Acids (a family of derivatives of neuraminic acid) are usually found as terminal structures of both N-linked and O-linked glycans.

To investigate whether changes in sialic acid levels contribute to the detrimental effect of storage on the ESR, cellular and plasma sialic acid levels were measured before and after storage and compared to the ESR.

This gene is used as a genetic marker for retinoblastoma and Wilson's disease. [provided by RefSeq, Feb 2009] Sialic acids comprise a family of more than 50 carbohydrates that share a nine-carbon backbone (C1-9) to which specific chemical modifications are enzymatically attached inside the cell. The most common sialic acid derivate found in mammals is N-Acetylneuraminic acid (Neu5Ac) which bears an acetyl group on the fifth carbon atom (C5).

av S Crunkhorn · 2011 — They found that the two sialic acids of the GD1a glycan docked with two out of three previously described Ad37 sialic acid binding sites and

The sialic acids are important molecules in the human body where it from the cell Sequential GC/MS analysis of sialic acids, monosaccharides, and amino acids of glycoproteins on a single sample as heptafluorobutyrate derivatives. Our SialEXO sialidase products are for removal & analysis of sialic acids. Enzymes are active on N- or O-linked glycans. Three different formats available. Titel: Sialic acid and binding by the human pathogen Helicobacter pylori.

The keto groups of the free sialic acids are derivatised with DMB using the Sialic acids in modern drug discovery: Introduction When surveying the literature, it is highly evident that there are many complementary methods for the development of new medicinal chemistry leads, based on a range of therapeutic targets. Sialic acid and its derivatives, and sialylated compounds (i.e. molecules conjugated to sialic acid) are already used as active pharmaceutical ingredients to prevent viral infections.

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
