Inducer Under normal circumstances, some reactions are very slow, and the reaction is accelerated when there is an inducer.For example, under acidic conditions, the oxidation rate of chlorine by potassium permanganate is very slow, and the oxidation rate is accelerated when there is Fe 2+.Wherein, Fe2+is the inductive conductor,potassium permanganateIt is an agent and chlorine is an attractant.Unlike catalytic reaction, the inducer participates in the reaction and becomes another substance.[1]

Vitamin C inducerIt is a derivative of vitamin C,molecular weightSmaller and more easily absorbed.It has high stability, is not easy to be oxidized by air, and has the beauty function of whitening and lightening spots, anti-oxidation, regulating sebum secretion, and promoting the formation of collagen.
history

In 1994, Shindo, a Japanese scholar, published a research that pointed out that vitamin C taken from diet can only be stored up to 1200 mg in the human body, and only 9% of it can reach the skin, which can not fully supply the skin that consumes a lot of VC in the living environment.
Only by local application, can vitamin C in the skin reach the level of inhibiting melanin and anti free radicals, completing whitening and preventing aging.Years of research also found that high purity vitamin C under normal conditions is very unstable, easy to oxidize and decompose, and cannot be stored for a long time, so the use effect cannot be guaranteed.

Therefore, the beauty industry has always dreamed of creating a vitamin C formula that can exist stably and meet the requirements of "effective and convenient" maintenance products.
Now, some cosmetic products have been adoptedVitamin C inducerTechnology.The other effects of vitamin C inducer need to be further developed.
Recent research shows that VC is crucial to human health:
1. Scurvy.The strength of vascular wall is closely related to VC.The microvessel is the smallest of all blood vessels. The wall of the microvessel may only have the thickness of one cell. Its strength and elasticity are determined by the collagen, which is responsible for connecting cells and has the function of glue.When VC is insufficient in the body, microvessels are easy to break and blood flows to adjacent tissues.If this happens on the skin surface, congestion and purple spots will occur;In vivo, it causes pain and joint swelling.In serious cases, there may be bleeding in the stomach, intestines, nose, kidneys and under the periosteum, even death.
2．Gingival atrophy, Bleeding.Healthy gums tightly wrap every tooth.Gingival is soft tissue, which is prone to atrophy and bleeding when lacking protein, calcium and VC.
3. PreventionArteriosclerosis。It can promote the excretion of cholesterol, prevent cholesterol from depositing on the inner wall of arteries, and even dissolve the deposited atherosclerotic plaque.
4. Treat anemia.It can reduce the trivalent iron that is difficult to be absorbed and utilized into divalent iron, promote the absorption of iron in the intestine, improve the utilization rate of iron in the liver, and contribute to the treatmentiron-deficiency anemia。
5. Cancer prevention.Rich collagen helps prevent the spread of cancer cells;The antioxidant effect of VC can resist the damage of free radicals to cells and prevent cell mutation;blocknitriteAnd secondary amine to form a strong carcinogen nitrosamine.It was once found that the VC content in patients who died of cancer was almost zero by dissection.
6. Protect cells, detoxify and protect the liver.In human life activities, it is very important to ensure the integrity of cells and normal metabolism.To this end,glutathioneAnd enzymes play an important role.Glutathione is a short peptide composed of glutamic acid, cystine and glycine, which has redox effect in the body.It exists in two forms, namely oxidation type and reduction type. The reduction type plays an important role in ensuring the integrity of the cell membrane.VC is a strongantioxidant, which is oxidizedOxidized glutathioneRestore toReduced glutathioneSo as to play an antioxidant role.Enzymes are catalysts for biochemical reactions. Some enzymes need free radicals (- SH) to remain active.VC can reduce the disulfide bond (- S-S) to - SH, thus improving the activity of related enzymes and playing the role of antioxidant.It can be seen from the above that as long as VC is sufficient, VC, glutathione and - SH form a powerful antioxidant combination to eliminate free radicals, prevent lipid peroxidation and the toxic effect of some chemicals, and protect the detoxification ability of the liver and the normal metabolism of cells.
7. Improve human immunity.Leukocytes are rich in VC. When the body is infected, the VC in the leukocytes decreases sharply.VC can be enhancedNeutrophilsThe chemotaxis and deformability of can improve the sterilization ability.PromotionLymphoblastIt can improve the body's recognition and killing of foreign and malignant cells.ParticipationimmunoglobulinSynthesis of.Improve the activity of CI complement esterase and increase the production of complement CI.Promote the production of interferon, interfere with the transcription of viral mRNA, and inhibit the proliferation of viruses.
8. Improve the emergency response capability of the body.The human body is subject to abnormal stimulation, such as severe pain, cold, hypoxia, and strong mental stimulation, which will lead to a tense state of resistance to abnormal stimulation.This state is associated with a range of bodies, including sympathetic excitation, increased secretion of adrenal medulla and corticosteroids.Adrenal medullaThe adrenaline andNorepinephrineIt is transformed from tyrosine, and VC is required to participate in this process.
vitamin CIs a kind ofWater-soluble vitamin(Its aqueous solution is acidic) The chemical formula is C6H8O6. The lack of this vitamin C in the human body will lead to bad blood, so vitamin C is also called ascorbic acid.vitamin CIt is easily oxidized by oxygen in the air.Vitamin C is contained in fresh fruits, vegetables and dairy products. For example, the content of vitamin C in fresh orange juice is about 500mg/L[2]。
