A pH‐Responsive Synthetic Receptor for Switchable Binding of Carbohydrates

open access: yesChemPlusChem, Volume 90, Issue 12, December 10, 2025.
A diaminocarbazole macrocyclic receptor, designed for disaccharide recognition in water, exhibits distinct binding properties under alkaline versus neutral pH conditions. Carbohydrates are selectively recognized under alkaline conditions, whereas release of the bound guest occurs at physiological pH, effectively behaving as a pH‐switchable carbohydrate

Comparative Genomics and Virulence Mechanisms to Identify Genes Related to Mucin O‐Glycan Degradation and Pathogenicity in a Potentially Multidrug‐Resistant Clostridium tertium Strain

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
The comparative genomic analysis provides information about how C. tertium HGMC01 strain cause disease through mucin glycan degradation, colonization, multidrug resistance, and modulation of immune responses. Moreover, this analysis data suggest that this strain interacts with host cells by degrading mucin in the gut, potentially through recognition or

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

open access: yes, 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 Nutritional Composition and Multi‐Omics Analysis of Raw Milk From Normande and Holstein Cows

open access: yesFood Frontiers, Volume 6, Issue 6, Page 3042-3058, November 2025.
Normande milk is characterized by high protein and fat content, whereas Holstein milk is distinguished by its high milk yield. However, few studies have reported on their compositional differences. Thus, we used physicochemical and multi‐omics techniques to investigate the compositional differences between Normande and Holstein raw milks. ABSTRACT Milk

Potential Effects of Three Forms of Sialic Acid on Intestinal Health in Obese Mice Fed With a High‐Fat Diet

open access: yesFood Frontiers, Volume 6, Issue 6, Page 3090-3107, November 2025.
A high‐fat diet impairs intestinal health by disrupting the mucus layer, widening epithelial gaps, triggering inflammation, and causing microbial dysbiosis, ultimately leading to obesity and metabolic disorders. Sialic acid interventionsparticularly bound forms (3ʹ‐SL and EBN)outperform free Neu5Ac in restoring microbial balance, alleviating ...

Cloning of hemagglutinin (HA) protein of influenza A virus - Potential for sialic acid linkage discrimination [PDF]

open access: yes, 2007
The initial step in infection of a cell by influenza A virus is the attachment of a virus particle to the target cell. This is accomplished by interaction of a glycoprotein, hemagglutinin (HA), found on the surface of the viral lipid membrane with cell ...

Purification of the lysosomal sialic acid transporter. Functional characteristics of a monocarboxylate transporter [PDF]

open access: yes, 1998
Sialic acid and glucuronic acid are monocarboxylated monosaccharides, which are normally present in sugar side chains of glycoproteins, glycolipids, and glycosaminoglycans.

Sialic acid acquisition in bacteria - one substrate many transporters [PDF]

open access: yes, 2016
The sialic acids are a family of 9-carbon sugar acids found predominantly on the cell-surface glycans of humans and other animals within the Deuterostomes and are also used in the biology of a wide range of bacteria that often live in association with ...

Acid and enzymatic hydrolysis of the internal sialic acid residue in native and chemically modified ganglioside GM1

open access: yesJournal of Lipid Research, 1996
The sialic acid of gangliosides not containing GalNAc (i.e., GM3, GD3) is readily hydrolyzed either enzymatically by sialidases or chemically in acid conditions.
