Brassinosteroids represent a class of plant hormones. More than 70 compounds have been isolated from plants. Currently 42 brassinosteroid metabolites and their conjugates are known. This review describes the miscellaneous metabolic pathways of brassinosteroids in plants. There are some types of metabolic processes involving brassinosteroids in plants: dehydrogenation, demethylation, epimerization, esterification, glycosylation, hydroxylation, side-chain cleavage and sulfonation. Metabolism of brassinosteroids can be divided into two categories: i) structural changes to the steroidal skeleton; and ii) structural changes to the side-chain.
油菜素甾醇是一类植物激素。已从植物中分离出70多种化合物。目前已知42种油菜素甾醇代谢物及其共轭物。这篇综述描述了植物中油菜素甾醇的各种代谢途径。植物中存在一些涉及油菜素甾醇的代谢过程:脱氢、去甲基化、差向异构化、酯化、糖基化、羟基化、侧链裂解和磺化。油菜素甾醇的代谢可分为两类:i)甾体骨架的结构变化;ii)侧链的结构变化。
