Vitamin E is a slightly yellow to yellow or yellow-green clear viscous liquid, almost odorless, and darkens when exposed to light. The natural type will solidify when placed, and will melt at about 25°C. It is a fat-soluble vitamin. There are 8 kinds of vitamins in nature, which are divided into 4 kinds of tocopherols and 4 kinds of tocotrienols. Vitamin E we usually say refers to α-tocopherol, which is a yellowish-green transparent viscous liquid, easily soluble in organic solvents, insoluble in water, stable to heat, extremely unstable to oxygen, and easy to be oxidized.
Vitamin E is a basic nutrient whose exact function is not yet known. It is an antioxidant. It can combine with selenium in the diet to prevent polyvalent unsaturated fatty acids in membranes and other cell structures and prevent free radical damage; protect red blood cells from hemolysis , Protect nerves and muscles from oxygen free Chemicalbook base damage, maintain the normal development and function of nerves and muscles. It may also be a cofactor for some enzyme systems. This product participates in some metabolic reactions in the body, can resist the peroxidation of free radicals, can resist aging, protect the skin, and can also enhance the ovarian function and prevent habitual abortion.
Tocopherol acetate is the esterification product of tocopherol (vitamin E) and acetic acid. It is not an estrogen, but a fat-soluble vitamin with antioxidant properties and stable performance.
