D‐Allulose is a rare monosaccharide structurally similar to D‐fructose, characterized by low caloric content and relatively high sweetness. This study aimed to conduct a 90‐day oral toxicity test to systemically evaluate the potential toxicological effects of D‐allulose produced via a novel one‐step fermentation process using genetically engineered ...

Membrane-bound glycerol dehydrogenase catalyzes oxidation of D-pentonates to 4-keto-D-pentonates, D-fructose to 5-keto-D-fructose, and D-psicose to 5-keto-D-psicose [PDF]
A novel oxidation of D-pentonates to 4-keto-D-pentonates was analyzed with Gluconobacter Thai-landicus NBRC 3258. D-Pentonate 4-dehydrogenase activity in the membrane fraction was readily inactivated by EDTA and it was reactivated by the addition of PQQ ...

Update: Enzymatische Synthese für industrielle Anwendungen
Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

An Update: Enzymatic Synthesis for Industrial Applications
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Crystal structure of 6-deoxy-α-l-psicofuranose
The title compound, C6H12O5, was crystallized from an aqueous solution of 6-deoxy-l-psicose (6-deoxy-l-allulose, (3S,4S,5S)-1,3,4,5-tetrahydroxyhexan-2-one), and the molecule was confirmed as α-furanose with a 3T4 (or E4) conformation, which is a ...
