Vitamin H, also known as biotin, coenzyme R, is a water soluble vitamin. Also belong to vitamin B family. It is necessary to synthesize vitamin C substances. And an indispensable substances for normal fat and protein metabolism.
Traits and stability: it is a colorless long needle crystals, with urea and thiophene fused ring, also with valerate side chain; very slightly soluble in water and ethanol, and insoluble in common organic solvents. In the medium-strength acid and neutral solutions can keep stable for several days, a poor stability in the alkaline solution. Fairly stable in normal temperature, but the high temperature and oxidizer can make it lose its activity. Studies by biotin supplier show that after oral biotin rapidly absorbed from the stomach and intestines, 80% of the biotin in blood exist in free form, distributed in the body tissues, liver, kidney’s content is the most, a lot of biotin unchanged in the urine discharged, only a small part of the biotin metabolism of the sulfur oxides and double down biotin.
Physiological role: Vitamin H combined with the enzyme involved in the fixing of carbon dioxide in the body and carboxylation processes, relate to important metabolic processes such as pyruvate carboxylation and in vivo is transformed into oxaloacetate, acetyl coenzyme A hydroformylation malonyl coenzyme A sugar and biochemical reactions in fat metabolism. It is also a growth factor for some microorganisms, a very small amount (0.005 ¼g) can make the test bacteria grow. For example, Alternaria mold growth requires a very small amount of biotin. Human need about 100 to 300 micrograms daily. Raw egg in a protein avidin and biotin, the combined biotin can not be absorbed by the digestive tract; cause the animal lack of biotin, appears to loss appetite, glossitis, dander, dermatitis, hair removal and so on. However, there is not any cases of human biotin deficiency may be due to the addition to the food source, therefore intestinal bacteria can also synthesize biotin.
Efficacy: Vitamin H is a key regulatory elements for glycogen gluconeogenesis, the combined effects of the fatty acids, and the metabolism of certain amino acids, and can play a role in promoting the synthesis of certain proteins by helping energy production; assist in cell growth at the same time, manufacturing fatty acid metabolism of carbohydrates, fats and proteins, and contribute to the use of vitamin B complex; promote sweat glands, nerve tissue, bone marrow, male gonads health; maintaining normal functioning and growth of skin and hair, relieve eczema , dermatitis symptoms; gray hair and hair loss prevention, treat baldness; ease muscle pain; helpful to depression and insomnia; also involved in vitamin B12, folic acid, pantothenic acid metabolism; promote urea synthesis and excretion; improve the body's immune function.
Researchers also found that biotin can promote the decomposition of fat and carbohydrates, to enable them to accelerate into the energy required by the human activities; such as an insufficient number of biotin in the body, the fat will accumulate in the body and cause obesity. This new discovery of biotin in weight loss, slimming class care products has laid a solid foundation, and opens up a broader market for biotin.
Meanwhile, the cosmetic raw material suppliers also found that the biotin with excellent cosmetic effect, can keep skin whitening, nail smooth and so on. This finding is also carve out a big pharmaceutical purposes for boitin. The cosmetics industry is one of the international industry, total sales of cosmetics international market is much higher than the sales of drugs, the new applications of biotin on biological skin, nail beauty and salons is bound to lead to the sales rising.
