WebJun 1, 2002 · Flavonols are among the most important flavonoids with respect to biological activity, and the gene duplication of FLS in Arabidopsis may provide a mechanism for controlling the types and amounts of flavonols produced in different tissues and in response to different environmental cues. WebJun 30, 2024 · 71 synthase (ANS). 72 The central enzyme of flavonol biosynthesis is flavonol synthase (FLS). FLS converts a 73 dihydroflavonol into the corresponding flavonol by introducing a double bond between C-2 and C-3 74 of the C-ring (Figure 1)(Forkmann et al., 1986; Holton et al., 1993). FLS activity was first identified
