维生素E(生育酚)是高等脊椎动物细胞正常分化与功能所需的四种脂溶性维生素之一。和缺乏其他营养成分所引起的疾病不同,缺乏维生素E在各种动物有各种不同的表现,涉及不同的器官。尽管缺乏维生素E常引起骨胳肌萎缩,但除羊和牛外,心脏的受累则较为少见和较不严重。维生素E的作用方式尚不肯定。现有三种学说:(1)抗氧化剂学说:维生素E作为一种生理性抗氧化剂,能保护组织中的多链不饱和脂肪酸和其他容易被氧化的基团(如巯基团)不受氧的影响。(2)呼吸链学说:维生
Vitamin E (tocopherol) is one of the four fat-soluble vitamins required for normal differentiation and function of higher vertebrate cells. In contrast to diseases caused by the lack of other nutrients, the lack of vitamin E has a variety of manifestations in a variety of animals, involving different organs. Although lack of vitamin E often causes skeletal muscle atrophy, heart involvement is rarer and less severe than sheep and cattle. The role of vitamin E is not yet sure. The existing three doctrines: (1) Antioxidant theory: Vitamin E as a physiological antioxidant, can protect tissue polyunsaturated fatty acids and other easily oxidized groups (such as mercapto groups) from the impact of oxygen . (2) respiratory chain theory: living
