The bioimprinting effect in sol‐gel immobilization of lipases was studied to develop efficient novel immobilized biocatalysts with significantly improved properties for biotransformations in continuous‐flow systems. The bioimprinting candidates were selected systematically among the substrate mimics already found in the active site of experimental lipase structures. Four lipases (Lipase AK, Lipase PS
The apple leaf midge and raspberry cane midge pheromones have been found to be acetoxyheptadecenone and acetoxyundecanone, respectively, and uses for the related C9-19 oxoalkyl or oxoalkenyl molecules substituted with a lower alkanoyloxy group are provided, including monitoring population levels of the midge and control of midge populations by disrupting mating patterns.
