Naringenin is a bitter, colourless flavanone, a type of flavonoid. It is the predominant flavanone in grapefruit, and is found in a variety of fruits and herbs.
Hesperetin is the 4'-methoxy derivative of eriodictyol, a flavanone. Hesperetin's 7-O-glycoside, hesperidin, is a naturally occurring flavanon-glycoside, the main flavonoid in lemons and sweet oranges. Hesperetin are not found to a significant extent in Citrus spp.
The flavanones, a type of flavonoids, are various aromatic, colorless ketones derived from flavone that often occur in plants as glycosides.
In enzymology, a flavanone 4-reductase (EC 1.1.1.234) is an enzyme that catalyzes the chemical reaction
Eriodictyol is a bitter-masking flavanone, a flavonoid extracted from yerba santa, a plant native to North America. Eriodictyol is one of the four flavanones identified in this plant as having taste-modifying properties, the other three being homoeriodictyol, its sodium salt, and sterubin.
Homoeriodictyol is a bitter-masking flavanone extracted from Yerba Santa a plant growing in America.
Sterubin (7-methoxy-3',4',5-trihydroxyflavanone) is a bitter-masking flavanone extracted from Yerba Santa a plant growing in America.
In enzymology, a flavanone 3-dioxygenase (EC 1.14.11.9) is an enzyme that catalyzes the chemical reaction
In enzymology, a chalcone isomerase is an enzyme that catalyzes the chemical reaction
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 enzymatic modifications to yield flavanones → dihydroflavonols → anthocyanins. Along this pathway, many products can be formed, including the flavonols, flavan-3-ols, proanthocyanidins (tannins) and a host of other various polyphenolics.
In enzymology, a flavanone 7-O-beta-glucosyltransferase is an enzyme that catalyzes the chemical reaction
In enzymology, a flavanone 7-O-glucoside 2"-O-beta-L-rhamnosyltransferase is an enzyme that catalyzes the chemical reaction
Sakuranetin is a flavan-on, the 7-methoxy derivative of naringenin, found in Polymnia fruticosa and rice, where it acts as a phytoalexin against spore germination of Pyricularia oryzae.
The flavan-4-ols (3-deoxyflavonoids) are flavone-derived alcohols and a family of flavonoids. Flavan-4-ols are colorless precursor compounds that polymerize to form red phlobaphene pigments. They can be found in the sorghum. Glycosides can be isolated from a methanol extract of the rhizomes of Abacopteris penangiana.
Apiforol is a chemical compound belonging to the flavan-4ol class of flavonoids.
The C-methylated flavonoids are a category of flavonoid having methylation(s) on carbon.
Retusin is an O-methylated flavonol, a type of flavonoid. It can be found in Origanum vulgare and in Ariocarpus retusus.
Neoeriocitrin is a flavanone-7-O-glycoside between the flavanone eriodictyol and the disaccharide neohesperidose.
Eriocitrin is a flavanone-7-O-glycoside between the flavanone eriodictyol and the disaccharide rutinose. It is commonly found in lemons. It is colloquially called lemon flavonoid or a citrus flavonoid, one of the plant pigments that bring color to fruit and flowers.
Narirutin is a flavanone-7-O-glycoside between the flavanone naringenin and the disaccharide rutinose.
