Retinol (RET-uh-methanol) is the scientific name for vitamin A, vitamin that is found only in animals. Appears as an orange-yellow powder, light brown with a cast and is a relatively stable compound. Retinol is converted in the body of an alcohol to corresponding aldehyde, retinal (C20H28O), one of the most important chemicals in the process, transformed by light into nerve impulses in the retina involved the eye. Vitamin A is necessary for a number of biochemical reactions in the body, including development and tissue growth and maintenance of the immune system.
Vitamin A is synthesized in the body of animals through various ways. An important source of vitamin A is a group of related compounds called carotenoids, substances responsible for the appearance of the yellow and orange fruits and vegetables such as carrots, sweet potatoes, pumpkins, melons, apricots, pumpkin and mango. Some green leafy vegetables such as kale, spinach and cabbage are also good sources of carotenoids. The most important of the carotenoids beta-carotene (beta carotene), C40H56. Oxidation of carotenoids in the organs of animals converted retinol.
Retinol Serum : Retinol
The chemical structure of retinol determined in 1931 by Swiss chemist Paul Karrer (1889% u20131971) and the compound was synthesized shortly after the Austria-German chemist Richard Kuhn (1900% u20131967). The first method work has been successfully developed for commercial production of retinol in the mid-1940s by German chemist Otto Isler (1920% u20131992), then with the pharmaceutical company Roche, in Sissein, Germany. Isler% u2019s place in a complex series of reactions that begins to do with the combination of a hydrocarbon, carbon fourteen and six carbon hydrocarbons to the basic framework to build on the molecule of retinol. Regular production of vitamin A began in 1948 with a planned production of 10 kg per month, which soon increased to 50 kg per month. Roche today Sissein system has continued to produce retinol.
Vitamin A is probably best known for her role in maintaining normal vision known. The shortcomings of the compound is likely to come much earlier in a variety of eye diseases, mostly night blindness. Night blindness is a disease in which one loses the ability to distinguish objects in dim light. If untreated, vitamin deficiency lead to a reduced ability to see in normal light, and eventually total blindness.
However, vitamin A has been shown to have a number of other functions in the body. It is important for growth, bone formation, to obtain reproductive, immune functioning and wound healing. have a number of other claims to make the connection, although the evidence is not as strong as it is for the above-mentioned functions. For example, to be effective in the prevention or treatment of a variety of Conditions such as measles, intestinal parasites, osteoporosis, inflammatory diseases of the intestine, bone marrow disorders, some types of cancer, tuberculosis, peritonitis, arthritis, food poisoning, disease, Alzheimer% u2019s disease, miscarriages, and HIV / AIDS. In any case, the evidence is not strong enough to see a clear link between retinol and disease, but is still under investigation, the strength of the association may determine. Retinol is commercially available in a variety of formulations such as tablets, capsules and creams. These products usually contain a modified form of retinol, which is easily absorbed by the body.
For example, a product is known as tretinoin, a synthetic form of retinol, as a trans-retinoic acid is known. The word all means of transportation retinoic acid all obligations to be doubled on the same side of
Molecule. Products with tretinoin for the treatment of acne, blackheads, wrinkles, pimples, freckles, sun spots, and precancerous lesions. They work by increasing the speed at which the skin makes the old cells and replaces them with new cells.
Supplementation with vitamin A in the form of tablets or capsules are available in two formulas, which contain retinol and available
such as beta-carotene. You can not become too much of this latter type of vitamin A. The body is not excessive amounts of carotene to retinol, but the withdrawal of excess in the urine or stool. Too much vitamin A-based retinol, however, can lead to health problems. Vitamin A is fat soluble, 05 stored in body fat and achieve relatively high concentrations to ingestion. An excess of retinol in the body, with liver damage, osteoporosis, skin rashes, fatigue, bone and joint pain, nausea, insomnia and personality changes be linked .
