Comparison of sialic acid content in bovine and buffalo milk and meat
Animal-origin food, such as meat and milk, are important sources of sialic acids (SIAs) with relevant implications for human health. Two significant SIAs in mammals are N-acetyl-neuraminic acid (Neu5Ac) and N- glycolylneuraminic acid (Neu-5Gc).

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.

Post-Glycosylation Modification of Sialic Acid and Its Role in Virus Pathogenesis
Sialic acids are a family of nine carbon keto-aldononulosonic acids presented at the terminal ends of glycans on cellular membranes. α-Linked sialoglycoconjugates often undergo post-glycosylation modifications, among which O-acetylation of N-acetyl ...

Sialic acids are located at the termini of mammalian cell-surface glycostructures, which participate in essential interaction processes including adhesion of pathogens prior to infection and immunogenicity. Here we present the synthesis and bioorthogonal

Interaction of solid organic acids with carbon nanotube field effect transistors [PDF]
A series of solid organic acids were used to p-dope carbon nanotubes. The extent of doping is shown to be dependent on the pKa value of the acids. Highly fluorinated carboxylic acids and sulfonic acids are very effective in shifting the threshold voltage and making carbon nanotube field effect transistors to be more p-type devices.
