WebPhenolic compounds are secondary metabolites involved in different protection mechanisms as, for example, against grazers, epiphytes and UV radiation. Seasonal variations of phenolic content in C. amentacea were analysed and laboratory experiments, in which C. amentacea was exposed to an increase of temperature (258C and 308C), … WebThe compound that is principally responsible for enzymatic browning of fruit and vegetables is PPO (EC. 1.10.3.1), which is a term designated for the group of enzymes that catalyzes the oxidation of phenolic compounds that produces a brown color on the cut surfaces of vegetables and fruit ( Whitaker and Lee, 1995 ). WebLarge number of phenolic compounds occur in plants as secondary metabolites which perform the following functions: (i) Some of them act as chemical deterrents against herbivores and pathogens. (ii) Plant phenolics such as lignins provide mechanical strength to the plants and have significant proective functions in them. ADVERTISEMENTS: re2 where to get arking garage keycard
