Synthesis of Sucrose-Mimicking Disaccharide by Intramolecular Aglycone Delivery

Molecules
Rare sugars are known for their ability to suppress postprandial blood glucose levels. Therefore, oligosaccharides and disaccharides derived from rare sugars could potentially serve as functional sweeteners.

Influence of Nonenzymatic Browning Reactions on the Digestibility and Gut Microbiota Fermentation of Starch and Protein

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 6, November 2025.
ABSTRACT Cooking has dramatic effects on the digestion and fermentation of food components. The changes that occur to starch and protein during nonenzymatic browning (NEB) have garnered attention due to health concerns. Among these changes, Maillard reaction, caramelization, and oxidation have major effects on starch and protein digestibility, as well ...

Der Ursprung der Bausteine des Lebens auf der Erde im Hadaikum

Angewandte Chemie, Volume 137, Issue 42, October 13, 2025.
Der Ursprung des Lebens im Hadaikum erforderte die Bildung von Aminosäuren und Nukleosiden als Schlüsselmoleküle des Lebens. In einer oft postulierten stark reduzierenden Atmosphäre bilden sich HCN und seine Derivate robust als plausible Ausgangsstoffe. Aber HCN bildet sich nicht in der schwach reduzierenden Atmosphäre des Hadaikums.

The Origin of the Feedstock Molecules for Life on the Hadean Earth

Angewandte Chemie International Edition, Volume 64, Issue 42, October 13, 2025.
The origin of life in the Hadean eon required the formation of amino acids and nucleosides among the key molecules of life. In an often postulated strongly reducing atmosphere, HCN and its derivatives are robustly formed as plausible starting molecules. But HCN does not form in a Hadean, weakly reducing atmosphere.

Critical approaches in the catalytic transformation of sugar isomerization and epimerization after Fischer－History, challenges, and prospects

Green Energy & Environment
The transformation of aldose to ketose or common sugars into rare saccharides, including rare ketoses and aldoses, is of great value and interest to the food industry and for saccharidic biomass utilization, medicine, and the synthesis of drugs. Nowadays,

Dihydroxyacetone metabolism in Haloferax volcanii

Frontiers in Microbiology, 2013
Dihydroxyacetone (DHA) is a ketose sugar that can be produced by oxidizing glycerol. DHA in the environment is taken up and phosphorylated to DHA-phosphate by glycerol kinase or DHA kinase.
