Sialic acids Neu5Ac and KDN in adipose tissue samples from individuals following habitual vegetarian or non-vegetarian dietary patterns

open access: yesScientific Reports, 2023
Sialic acids (Sias) are a class of sugar molecules with a parent nine-carbon neuraminic acid, generally present at the ends of carbohydrate chains, either attached to cellular surfaces or as secreted glycoconjugates.

Assessment of Sialic Acid Content in Dairy Products from Buffalo’s and Goat’s Milk Compared to Cow’s Milk

open access: yesDairy
Sialic acids (SIAs) are bioactive compounds present in glycoproteins and glycolipids, playing key roles in human physiology. N-acetylneuraminic acid (Neu5Ac), the only sialic acid synthesized by humans, contributes to neurodevelopment and immune function,

A systematic review reveals conflicting evidence for the prevalence of antibodies against the sialic acid ‘xenoautoantigen’ Neu5Gc in humans and the need for a standardised approach to quantification

open access: yesFrontiers in Molecular Biosciences
Despite an array of hypothesised implications for health, disease, and therapeutic development, antibodies against the non-human sialic acid N-glycolylneuraminic acid (Neu5Gc) remain a subject of much debate.

Polyclonal human antibodies against glycans bearing red meat-derived non-human sialic acid N-glycolylneuraminic acid are stable, reproducible, complex and vary between individuals: Total antibody levels are associated with colorectal cancer risk.

open access: yesPLoS ONE, 2018
BackgroundN-glycolylneuraminic acid (Neu5Gc) is a non-human red-meat-derived sialic acid immunogenic to humans. Neu5Gc can be metabolically incorporated into glycan chains on human endothelial and epithelial surfaces. This represents the first example of

The Sodium Sialic Acid Symporter From Staphylococcus aureus Has Altered Substrate Specificity

open access: yesFrontiers in Chemistry, 2018
Mammalian cell surfaces are decorated with complex glycoconjugates that terminate with negatively charged sialic acids. Commensal and pathogenic bacteria can use host-derived sialic acids for a competitive advantage, but require a functional sialic acid ...

The determination of n-acetylneuraminic acid (neu5ac) and n-glycolyl-neuraminic acid (neu5gc) types of sialic acids in hematopoietic organ of the silkworm, bombyx mori l. (lepidoptera: bombycidae)

open access: yesKafkas Universitesi Veteriner Fakültesi Dergisi, 2012
In insects, for a long time, it was generally accepted that members of insect do not have sialic acids which are typical terminal glycans of cells surface glycolipids and glycoproteins, and thus especially important in cell interactions and signaling events.

Characterization of an Aptamer Targeting Neu5Gc, as an Endogenous Pathogenic Factor Derived from Red Meat

open access: yesMolecules
N-glycolylneuraminic acid (Neu5Gc), a sialic acid predominantly found in the non-neurohumoral fluids of hind-mouthed animals, is incapable of synthesizing Neu5Gc due to a deletion in the CMAH exon of the gene encoding human CMP-Neu5Gc hydroxylase.

Molecular characterization of cytidine monophospho-N-acetylneuraminic acid hydroxylase (CMAH) associated with the erythrocyte antigens in dogs

open access: yesCanine Genetics and Epidemiology, 2019
Background N-glycolylneuraminic acid (Neu5Gc) is synthesized from its precursor N-acetylneuraminic acid (Neu5Ac) by cytidine-5′-monophospho-N acetylneuraminic acid hydroxylase (CMAH), which is encoded by the CMAH gene.

Screening and Characterization of Sialic Acid-Binding Variable Lymphocyte Receptors from Hagfish

open access: yesBioTech
Sialic acid is a diverse group of monosaccharides often found on the termini of N- and O-linked glycans as well as being components of glycoconjugates.

Changes in the Serum and Tissue Levels of Free and Conjugated Sialic Acids, Neu5Ac, Neu5Gc, and KDN in Mice after the Oral Administration of Edible Bird’s Nests: An LC–MS/MS Quantitative Analysis

open access: yesSeparations
Edible bird’s nests have a variety of biological activities, the main components of which are sialic acids. Sialic acids are a group of nine-carbon N-acetylated derivatives of neuraminic acid containing a keto group at position C2 and play important ...
