· as an antioxidant, vitamin e acts as a peroxyl radical scavenger, preventing the propagation of free radicals in tissues, by reacting with them to form a tocopheryl radical, which will then be reduced by a hydrogen donor (such as vitamin c) and thus return to its reduced state.
· as an enzymatic activity regulator, for instance, protein kinase c (pkc), which plays a role in smooth muscle growth, can be inhibited by α-tocopherol.
· vitamin e also has an effect on gene expression. macrophages rich in cholesterol are found in the atherogenetic tissue.
· vitamin e also plays a role in neurological functions,and inhibition of platelet aggregation
