Sampling and Analytical Method for Alpha-Dicarbonyl Flavoring Compounds via Derivatization with o-Phenylenediamine and Analysis Using GC-NPD

Scientifica, 2016
A novel methodology is described for the sampling and analysis of diacetyl, 2,3-pentanedione, 2,3-hexanedione, and 2,3-heptanedione. These analytes were collected on o-phenylenediamine-treated silica gel tubes and quantitatively recovered as the ...

In Helicobacter pylori auto-inducer-2, but not LuxS/MccAB catalysed reverse transsulphuration, regulates motility through modulation of flagellar gene transcription. [PDF]

, 2010
BACKGROUND: LuxS may function as a metabolic enzyme or as the synthase of a quorum sensing signalling molecule, auto-inducer-2 (AI-2); hence, the mechanism underlying phenotypic changes upon luxS inactivation is not always clear.

Integrated exploration of molecular structure, quantum chemical properties, molecular docking, and antioxidant activity of 4-(2-hydroxyanilino)pent-3-en-2-one

Results in Chemistry
Schiff bases are crucial intermediates in organic chemistry. They are used to introduce carbon–nitrogen double bonds in organic molecules. In this study, 4-(2-hydroxyanilino) pent-3-in-2-one (L) was synthesized from the reaction of 2,4-pentanedione and 2-
