Flavonoids are synthesized by the phenylpropanoid metabolic pathway in which the amino acid phenylalanine is used to produce 4-coumaroyl-CoA. This can be combined with malonyl-CoA to yield the true backbone of flavonoids, a group of compounds called chalcones, which contain two phenyl rings. Conjugate ring-closure of chalcones results in the familiar form of flavonoids, the three-ringed structure of a flavone. The metabolic pathway continues through a series of enzym…

WebJun 1, 2001 · The question of the intracellular localization and organization of flavonoid enzymes was first raised by Helen Stafford more than 25 years ago, together with the suggestion that the enzymes of general phenylpropanoid, sinapate, lignin, and flavonoid biosynthesis were likely to function as multienzyme complexes (Stafford, 1974). The … WebSep 28, 2024 · Flavonoids are a wide class of polyphenols with multiple biological activities. Unfortunately, many mechanisms of action that explain these activities are still unknown or there are insufficient data on their pharmacokinetics. Moreover, there are even undiscovered aspects about flavonoid biosynthesis. Expanding the knowledge on these topics will … in flow meter
