维生素E是对动物体十分重要的脂溶性维生素。动物对维生素E的利用需要经过肠道的吸收、血液中脂蛋白的转运、肝脏的储存和调控及机体各个组织的摄取和代谢;这些过程涉及到多种生理学机制,包括多种载体的转运、酶类的催化及其他营养素的互作等。了解这些机制有助于人们探索动物体利用维生素E的关键点,继而通过调控这些关键点促进动物对维生素E的利用。作者简要总结了有关维生素E在动物及人类体内吸收、转运、代谢过程机理的最新研究结果。
Vitamin E is a kind of fat-soluble vitamins which is of great importance to animals.Vitamin E is utilized by intestinal absorption,lipoprotein transport,storage and regulation in the liver and the uptake and metabolism in varies of tissues.The mechanism is involved in those processes,including the transport of various transporters,catalysis of enzymes and the interaction between different nutrients.Understanding of the mechanism would better to discover the key point in vitamin E utilization and therefore to facilitate vitamin E utilization by regulating the key point.This review briefly summarizes the research advances of the mechanisms involved in vitamin E absorption,transport and metabolism.
