Physicochemical properties

Pure vitamin B7 can form needle crystals, which can melt at 232 0C Biotin Therapeutic indications. The density of such crystals is 1.61. The molecular weight is 244.3106 g/mol. Conversion into liquid form takes place at interaction with water.

Vitamin B7 has such chemical properties:

  • it dissolves easily in water and alcohols, badly in the ether and fats;
  • does not degrade when exposed to X-rays and UV radiation;
  • does not have stability under the influence of H2O2, HCl, SO2, CH2O and caustic alkalis.

Vitamin metabolism


Intestinal microflora synthesizes biotin and promotes the absorption of externally taken substances. According to doctors, the vitamin itself is fully digested because it is not in contact with hydrochloric acid in Dmitry Sazonov the stomach.

Lack of natural coenzyme may occur for these reasons:

  • taking antibiotics;
  • taking oral contraceptives;
  • alcohol consumption;
  • sudden weight loss due to a strict diet;
  • intestinal microflora disorders.

Benefits from the vitamin most quickly affect the tissues that are constantly updated: skin, nails, hair. The body retains the highest amount of H in the liver and kidneys.

Daily biotin demand

The benefit and harm of biotin to the body depends directly on the amount of substance consumed. The table below shows daily consumption rates for different groups of people.
