1, vitamin c
Known as the closest partner of skin, it promotes the metabolism of tyrosine and tryptophan in amino acids and prolongs the life of the body. It is an essential component of skin intercellular substance. Therefore, the integrity of skin tissue, the maintenance of normal permeability of blood vessels and the balance of pigment metabolism are inseparable from it.
The main function of vitamin C is to help the human body complete the redox reaction, thus improving brain power and intelligence. According to Nobel Prize winner Pauling, taking large doses of vitamin C has a certain effect on preventing colds and fighting cancer.
2. Tocopherol
Vitamin e oxidizes easily. Therefore, it can protect other oxidizable substances (such as vitamin A and unsaturated fatty acids) from being destroyed. Vitamin E in food is mainly absorbed in the upper small intestine of animals, and is mainly carried by β -lipoprotein in blood and transported to various tissues. It is recognized that it has anti-aging effect, can promote skin blood circulation and granulation tissue growth, make hair and skin smooth and smooth wrinkles.
Extended data
The principle of anti-oxidation is:
Antioxidant is any substance that can effectively inhibit the free radical oxidation reaction at low concentration. Its mechanism of action can be directly acting on free radicals or indirectly consuming substances that are easy to produce free radicals to prevent further reactions.
When the human body inevitably produces free radicals, it also naturally produces antioxidant substances that resist free radicals to offset the oxidative attack of free radicals on human cells. The antioxidant system of human body is a perfect and complex system, which can be comparable to the immune system. The stronger the body's antioxidant capacity, the healthier it is and the longer its life span.
In human body, vitamin C is an effective antioxidant, and its antioxidant function is achieved by reducing the oxidative stress of ascorbic acid peroxidase substrate. The esterified form of vitamin E can delay photoaging, prevent sunburn and inhibit the formation of sunburn by eliminating excessive oxygen free radicals caused by external factors such as ultraviolet rays and air pollution.
