Biotin (Biotin) is one of the vitamin B complex, also known as vitamin H, vitamin B7, coenzyme R (Coenzyme R) and so on. Biotin in the liver, kidney, yeast, more content in milk is an important factor in organisms fixed carbon dioxide. Easy to combine with a protein in egg white, eat lots of raw protein can hinder the absorption of biotin leads to biotin deficiency, such as hair removal, weight loss, dermatitis. Biotin, also known as vitamin H, belongs to a water-soluble vitamin B group. Biotin is an essential substance metabolism, but also maintain the normal growth, development and health of essential nutrients, can not by artificial synthesis.
Biotin is a coenzyme of Composition, involved in energy metabolism and amino acids, can promote healthy skin and mucous membranes, and also help utilize the vitamin B group.

Biotin plays an important role in fat synthesis, gluconeogenesis pathway and other biochemical reactions. Biotin is a cyclic urea of chemical substances like, having a thiophenol (Thiophene) ring structure, such chemicals are eight isomorphic isomers, but only the right-handed biotin (d-biotin) is present in the nature, but also have the function of vitamins Biotin is a colorless, needle-like material, slightly soluble in cold water, more soluble in alcohol at, but insoluble in organic solvents. Biotin fairly stable to heat, not to be destroyed by acids or bases. Biotin in the small intestine to absorb very well, every cell can be said to contain some promise biotin, especially in the liver and kidney tissues will be more content. The protein contains raw egg protein (avidin), this protein is an anti-substance (antagonist), can be combined with biotin and biotin, which is not absorbed by the intestine, it can not play a normal biochemical effect. Fortunately, if the eggs cooked through, you can fight the destruction of such agents, it will not cause a lack of nutrition, so the eggs, especially protein, is not eaten raw.
