Synthesis of N-Glycolylneuraminic Acid (Neu5Gc) and Its Glycosides [PDF]

open access: yesFrontiers in Immunology, 2019
Sialic acids constitute a family of negatively charged structurally diverse monosaccharides that are commonly presented on the termini of glycans in higher animals and some microorganisms.

Absence of Neu5Gc and Presence of Anti-Neu5Gc Antibodies in Humans—An Evolutionary Perspective [PDF]

open access: yesFrontiers in Immunology, 2019
The glycocalyx of human cells differs from that of many other mammals by the lack of the sialic acid N-glycolylneuraminic acid (Neu5Gc) and increased abundance of its precursor N-acetylneuraminic acid (Neu5Ac).

The Role of Non-Human Sialic Acid Neu5Gc-Containing Glycoconjugates in Human Tumors: A Review of Clinical and Experimental Evidence. [PDF]

open access: yesBiomolecules
N-Glycolylneuraminic acid (Neu5Gc) is a sialic acid variant commonly found in most mammals but not synthesized by humans due to an inactivating mutation in the CMP-Neu5Ac hydroxylase (CMAH) gene. Despite this, Neu5Gc-containing molecules are consistently

Aptamer-CRISPR/Cas12a-Based Lateral Flow Technique for Visualized Rapid Detection of Endogenous Damage Factor Neu5Gc in Red Meat. [PDF]

open access: yesFoods
The N-glycolylneuraminic acid (Neu5Gc), a major salivary acid molecule found on the cell surface of animals such as pigs, cows, and sheep, can be metabolically incorporated into the body through consumption of animal-derived foods like red meat.

Species-specific N-glycan patterns in animal and human breast milk samples. [PDF]

open access: yesFront Nutr
The main components of milk are protein, fat and carbohydrates. Glycans are complex carbohydrate structures covalently bound to proteins and lipids or exist freely in solutions.

Inactivation of the CMAH gene and deficiency of Neu5Gc play a role in human brain evolution. [PDF]

open access: yesInflamm Regen
During human evolution, some genes were lost or silenced from the genome of hominins. These missing genes might be the key to the evolution of humans’ unique cognitive skills. An inactivation mutation in CMP-N-acetylneuraminic acid hydroxylase (CMAH) was

Variability of Sialic Acids in Beef Breeds and Nutritional Implications in Red Meat. [PDF]

open access: yesMolecules
This study examines the variability of sialic acids, specifically N-acetylneuraminic acid (Neu5Ac) and N-glycolylneuraminic acid (Neu5Gc), in beef from seven cattle breeds (Holstein Friesian, Red Pied, Maremmana, Chianina, Charolais, Limousin, and ...

Detection of N-glycolyl-neuraminic acid-containing glycolipids in human skin

open access: yesFrontiers in Immunology, 2023
Humans lack the enzyme that produces the sialic acid N-glycolyl neuraminic acid (Neu5Gc), but several lines of evidence have shown that Neu5Gc can be taken up by mammalian food sources and replace the common human sialic acid N-acetyl neuraminic acid ...

Preferential Accumulation of 14C-N-Glycolylneuraminic Acid over 14C-N-Acetylneuraminic Acid in the Rat Brain after Tail Vein Injection. [PDF]

open access: yesPLoS ONE, 2015
The two main molecular species of sialic acid existing in nature are N-acetylneuraminic acid (Neu5Ac) and N-glycolylneuraminic acid (Neu5Gc). Neu5Ac is abundant in mammalian brains and plays crucial roles in many neural functions.

N-glycolylneuraminic acid as a carbohydrate cancer biomarker

open access: yesTranslational Oncology, 2023
One of the forms of aberrant glycosylation in human tumors is the expression of N-glycolylneuraminic acid (Neu5Gc). The only known enzyme to biosynthesize Neu5Gc in mammals, cytidine-5′-monophosphate-N-acetylneuraminic acid (CMAH), appears to be ...
