2002年1月1日 · Anthocyanidin synthase (ANS), a 2-oxoglutarate iron-dependent oxygenase, catalyzes the penultimate step in the biosynthesis of the anthocyanin class of flavonoids. The crystal structure of ANS reveals a multicomponent active site containing metal, cosubstrate, and two molecules of a substrate analog (dihydroquercetin).

2020年11月5日 · Anthocyanin acyltransferase transfers an acyl group to a single position, such that Gt5,3'AT possesses a unique enzymatic activity. Structural investigation of this aromatic acyl group transfer is fundamental to understand the molecular mechanism of the …

2024年6月1日 · The formation of starch-anthocyanins complexes can be confirmed from the chemical structure, iodine binding capacity, crystal structure, apparent morphology, and the variation of thermodynamic properties and retrogradation properties of the complexes.

2024年2月15日 · Here, we propose a facile strategy to achieve the improved stability of anthocyanins encapsulated in γ-cyclodextrin metal-organic frameworks (CD-MOFs) with an in-depth exploration of their structure–property relationships.

Anthocyanins are water-soluble compounds based on a tricyclic flavonoid core and are known to function as pigments involved in determining the color of flowers, leaves, seeds and fruits (Offen et al., 2006; Tanaka et al., 2008).

2005年8月10日 · Here we describe the X-ray crystal structure of the cornflower pigment, which reveals that its blue colour arises from a complex of six molecules each of anthocyanin and flavone, with one...

1 天前 · Jiang et al. (2020) found that the crystal structure of the complex film based on CMC/starch and purple sweet potato anthocyanins was changed by the electrostatic interaction between starch, CMC, and PSPA, thereby reducing the light transmittance .

2024年11月8日 · The direct and indirect antioxidant action of anthocyanins, the question of the specificity of anthocyanin action in complex extracts, as well as limitations of cellular in vitro assays and biomarkers used for the detection of antioxidant effects of …

Anthocyanins, synthesized via the flavonoid pathway, are a class of crucial phenolic compounds which are fundamentally responsible for the red color of grapes and wines. As the most important natural colorants in grapes and their products, anthocyanins are also widely studied for their numerous beneficial effects on human health.

2023年8月31日 · Through biochemical and structural analysis, here we show that anthocyanin-related glutathione transferases, currently implicated only in anthocyanin transport, catalyse an essential...
