General description

N-Glycolylneuraminic acid (Neu5Gc) is a nonhuman sialic acid molecule synthesized in pigs but not in humans, that has a role as a mammalian metabolite and an antigen. This hydroxylated form of sialic acid, specifically N-acetylneuraminic acid, features a glycolyl substituent on nitrogen and a beta-configuration at the anomeric center. The biosynthesis of N-glycolylneuraminic acid involves the enzymatic activity of cytidine monophosphate-N-acetylneuraminate (CMP-Neu5Ac) hydroxylase.
In humans, the absence of endogenous production results from a gene mutation affecting CMP-Neu5Ac hydroxylase, the enzyme responsible for converting N-acetylneuraminic acid into Neu5Gc. However, Neu5Gc can accumulate in human cells through external ingestion from dietary sources like red meat and dairy products. N-Glycolylneuraminic acid is a versatile compound that finds application in cell biology, metabolomics and biochemical research

Application

N-Glycolylneuraminic acid has been used:
  • as a sugar in microtiter biofilm methodologic approach for the enhancement of biofilm formation
  • as a standard for the determination of sialic acids in the nervous system of silkworm and to find the variations of sialic acids among different developmental stages.
  • as a standard in the high-performance liquid chromatography (HPLC) analyses to detect the molecular species of sialic acid (Sia) species using 1,2-diamino-4,5-methylenedioxy-benzene (DMB) as a fluorogenic compound

Biochem/physiol Actions

N-Glycolylneuraminic acid (Neu5Gc) functions as an important tool for profiling anti-Neu5Gc antibodies and sialic acid-binding proteins.

Features and Benefits

  • Ideal for Metabolomics, Biochemical and Cell Biology research
  • Versatile and adaptable for wide variety of laboratory and research applications

Gangliosides are glycosphingolipids found on the cell surface. They act as recognition molecules or signal modulators and regulate cell proliferation and differentiation. N-glycolylneuraminic acid (NeuGc)-containing gangliosides have been detected in some neoplasms in humans, although they are usually absent in

A number of carbohydrate structures apart from Galα1-3Galβ1-4GlcNAc (Gal) have been implicated as potential xenoantigens. Epitopes of another carbohydrate structure, namely N-glycolylneuraminic acid (NeuGc), are widely expressed on the surfaces of endothelial cells of all mammals, except humans, and are
