Functional Characterization of a Flavone Synthase That Participates in a Kumquat Flavone Metabolon [PDF]
Frontiers in Plant Science, 2022 Flavones predominantly accumulate as O- and C-glycosides in kumquat plants. Two catalytic mechanisms of flavone synthase II (FNSII) support the biosynthesis of glycosyl flavones, one involving flavanone 2-hydroxylase (which generates 2-hydroxyflavanones for C-glycosylation) and another involving the direct catalysis of flavanones to flavones for O ...

Dietary flavonoid intake and incidence of erectile dysfunction [PDF]
, 2016 Background: The predominant etiology for erectile dysfunction (ED) is vascular, however limited data are available on the role of diet. A higher intake of several flavonoids reduces diabetes and cardiovascular disease (CVD) risk but no studies have ...

Mechanism and Application of Baker–Venkataraman O→C Acyl Migration Reactions [PDF]
, 2014 This literature review focuses on the O→C acyl migration of aryl esters to yield the corresponding 1,3-dicarbonyl products—a reaction known as the Baker–Venkataraman rearrangement—and outlines their subsequent transformations.
