Stilbene synthase resveratrol
WebJan 21, 2016 · Resveratrol (3,4′,5-trihydroxy-trans-stilbene, RSV) has emerged as an important molecule in the biomedical area. This is due to its antioxidant and health benefits exerted in mammals. Nonetheless, early studies have also demonstrated its toxic properties toward plant-pathogenic fungi of this phytochemical. Both effects appear to be opposed … WebResveratrol (3,5,4′-trihydroxy- trans -stilbene) is a stilbenoid, a type of natural phenol, and a phytoalexin produced by several plants in response to injury or when the plant is under attack by pathogens, such as bacteria or fungi.

WebResveratrol is a polyphenolic antioxidant that belongs to the stilbene family. Resveratrol is induced in grapevine in response to pathogens attacking the precursor molecules of malonyl-coenzyme A (CoA), p-coumaroyl CoA and the enzyme stilbene synthase [78]. Resveratrol may also be present in grapes, blueberry, cranberry, and bilberry.
