性质

性状:淡黄色或褐色油状或微黏稠液体,几乎无臭。熔点2.5-3.5℃,沸点200-220℃(13帕),相对密度(25/4℃)0.950,折光率1.5045。脂溶性,易溶于醇、醚、丙酮、氯仿、油脂及其他脂肪溶剂,几乎不溶于水。无氧存在时对热中碱都很稳定,100℃以下与酸无作用,但易被氧化,露置光线中色渐变深,有铁盐和银盐存在能加速其氧化。在空气中经光照或用化学试剂都可将它氧化成醌的衍生物。存在于植物油中,如小麦胚芽、玉米、向日葵籽、油菜籽、大豆油中,常与β-型、γ-型并存。

Biochem/physiol Actions
Tocopherols (TCP) (vitamin E) are a series (α, β, γ and δ) of chiral organic molecules that vary in their degree of methylation of the phenol moiety of the chromanol ring. Tocopherols are lipid soluble anti-oxidants that protect cell membranes from oxidative damage. α-Tocopherol is the form of tocopherol preferentially absorbed by homo sapiens. Various isofroms and analogues of tocopherol have opposing and differentiated regulatory activities in vivo.


Physical properties
This product is miscible with chloroform or ethanol. It is practically insoluble in water but it is miscible with ether, acetone, and vegetable oils. It is unstable to alkaline conditions.
