茶叶品质与茶树次级代谢及其产物有密切相关。次级代谢(Secondary metablism)是与初级代谢相对而言的,从底物(如糖)开始,经糖酵解和三羧酸循环、以及磷酸戊糖支路进行底物降解和末端氧化的过程称为初级代谢。初级代谢与茶树的生长发育和繁殖直接相关,并为其提供能源和中间产物。初级代谢的关键中间产物与蛋白质代谢、脂肪代谢,核酸代谢相联结。而次级代谢与植物的生存、生长、繁殖通常认为无直接关系,也不参与 Tea quality and tea secondary metabolites and their products are closely related. Secondary metablism is a process in which, relative to the primary metabolism, substrate (eg, sugar), undergoes glycolysis and tricarboxylic acid cycles, and pentose phosphate branches for substrate degradation and terminal oxidation Known as primary metabolism. Primary metabolism is directly related to the growth and reproduction of tea trees and provides them with energy and intermediates. The key intermediates of primary metabolism are associated with protein metabolism, fat metabolism, and nucleic acid metabolism. Secondary metabolism and plant survival, growth, reproduction is generally considered not directly related, nor involved
