Misleading measures in Vitamin D analysis: a novel LC-MS/MS assay to account for epimers and isobars [PDF]
Background Recently, the accuracies of many commercially available immunoassays for Vitamin D have been questioned. Liquid chromatography tandem mass spectrometry (LC- MS/MS) has been shown to facilitate accurate separation and quantification of the ...

This review highlights the powerful synergy between mechanochemistry and solid reagents to replace hazardous substances traditionally used in organic synthesis. Such an approach offers a safer and more sustainable pathway for conducting organic reactions, with potential benefits in both reactivity and selectivity. The use of solid bases, acids, and gas

Model for the non‐PTS utilization of manno‐oligosaccharides by Cellvibrio japonicus. The Mgp130A and EpiA enzymes are essential for the utilization of mannose residues. ABSTRACT Manno‐oligosaccharides and their metabolism play important roles in gut health, pharmaceutical development, and renewable chemical production.

Chemical synthesis of rare carbohydrates
Rare carbohydrates (e.g. D-tagatose, D-allulose, and D-xylulose) are regarded as ideal sugar replacers in a number of food formulations due to their relative sweetness and caloric value.

A comprehensive glycosylation study of diversely protected and activated d‐idopyranosyl and 6‐deoxy‐d‐ido‐heptopyranosyl donors using intra‐ and intermolecular coupling strategies is reported. Intramolecular aglycon delivery afforded 1,2‐cis‐β‐idopyranosides, while intermolecular glycosylation yielded chromatographically separable α‐ and β‐linked ...

Determinants of Glycosaminoglycan (GAG) Structure
Proteoglycans (PGs) are glycosylated proteins of biological importance at cell surfaces, in the extracellular matrix, and in the circulation. PGs are produced and modified by glycosaminoglycan (GAG) chains in the secretory pathway of animal cells.

Regio- and Stereoselective Ruthenium Catalyzed Hydrovinylation of 1,3-Dienes: Application to the Generation of a 20S-Steroidal Sidechain [PDF]
The addition of ethylene to 1,3-dienes and 1-vinylcycloalkenes, catalyzed by two ruthenium complexes, proceeds in a regioselective fashion to afford 3-methyl-1,4-dienes as products. For a steroidal-based 1-vinylcycloalkene, the addition is stereospecific,
