Fig. 5

A general schematic diagram of flavonoid biosynthetic, with emphasis on flavones (apigenin, luteolin, tricetin), flavonols (kaemperol, quercetin, myrcetin), and anthocyanins (pelargonidin, cyanidin, delphinidin; not shown are peonidin, malvidin, and petunidin, but peonidin is a derivative of the cyanindin pathway and malvidin and petunidin are derivatives of the delphinidin pathway). Enzymes that catalyze reactions in the Anthocyanin Biosynthetic Pathway include: ANS, anthocyanidin synthase; CHI, chalcone isomerase; CHS, chalcone synthase; DFR, dihydroflavonol 4-reductase; F3H, flavanone 3-hydroxylase; F3'H, flavonoid 3' -hydroxylase; F3'5' H, flavonoid 3',5'-hydroxylase; FLS, flavonol synthase; FNS, flavone synthase; UF3GT, UDP glucose flavonoid 3-glucosyltransferase
