• The glycoside-bound form is the most common flavone and flavonol form consumed in the diet. (wikipedia.org)
  • The substitution pattern of the central ring along with the degree of unsaturation and the oxidation of the flavonoid structure resolve this group of compounds into six main classes: flavonol, flavone, flavanonol, flavanone, anthocyanin, and isoflavonoid. (rsc.org)
  • According to the IUPAC nomenclature, they can be classified into: flavonoids or bioflavonoids isoflavonoids, derived from 3-phenylchromen-4-one (3-phenyl-1,4-benzopyrone) structure neoflavonoids, derived from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins (flavones and flavonols). (wikipedia.org)
  • The three flavonoid classes above are all ketone -containing compounds and as such, anthoxanthins ( flavones and flavonols ). (venalex.pl)
  • The goals of this study were to identify expressed sequence tags (EST) in Citrus sinensis (L.) Osbeck corresponding to genes involved in general phenylpropanoid biosynthesis and the key genes involved in the main flavonoids pathways (flavanones, flavones, flavonols, leucoanthocyanidins, anthocyanins and isoflavonoids).

  • Genes related to pathways such as fatty acid degradation, phenylpropanoid biosynthesis, and ABC transporters showed regulatory mechanisms governing internal flavonoid biosynthesis, transport, and tissue concentration, ultimately resulting in higher flavonoid concentrations in tomato leaves.

  • Flavonoid biosynthesis is one of the most studied branches of phenolic compounds, encompassing more than 4,000 different substances distributed within the plant kingdom. (scielo.br)
  • A thorough analysis of all related putative genes from the Citrus EST (CitEST) database revealed several interesting aspects associated to these pathways and brought novel information with promising usefulness for both basic and biotechnological applications. (scielo.br)
  • Thus, there is a need for highly ordered regulatory mechanisms determining the fate of each cell. (biomedcentral.com)
  • The glycoside-bound form is the most common flavone and flavonol form consumed in the diet. (wikipedia.org)
  • 2001). The common steps of phenylpropanoid pathway are catalyzed by phenylalanine ammonia- lyase (PAL), cinnamate 4-hydroxylase (C4H) and 4-coumarate:CoA ligase (4CL). (scielo.br)
  • Our study focused on determining growth parameters, such as cell size, and assessing the concentration of hormones. (preprints.org)
