WebChrysanthemic acid (NSC 11779) is an organic compound that is associated with a variety of natural and synthetic insecticides for the prevention of insect-borne diseases, among … WebThe first step in the biosynthesis of chrysanthemic acid was elucidated by Rivera et al. ( 2001 ), who showed that chrysanthemyl diphosphate is made by linking two dimethylallyl diphosphate (DMAPP) molecules in a reaction catalyzed by chrysanthemyl diphosphate synthase (CDS). Chrysanthemic acid is an organic compound that is related to a variety of natural and synthetic insecticides. It is related to the pyrethrin I and II, as well as the pyrethroids. One of the four stereoisomers, (1R,3R)- or (+)-trans-chrysanthemic acid (pictured), is the acid part of the ester pyrethrin I, which occurs naturally in the … See more Chrysanthemic acid is derived from its pyrophosphate ester, which in turn is produced naturally from two molecules of dimethylallyl diphosphate.
