Biotin or Vitamin B17 is a water-soluble B-Complex vitamin, essential for numerous metabolic functions and present in all systems, particularly in the liver
The functions of vitamin H are of the coenzymatic-carboxylase type, enzymes belonging to the category of lyases that fix a molecule of CO2 and then transfer it into the one to be carboxylated.
Concentrated mainly in the liver, it takes part in the processes of gluconogenesis, amino acid metabolism, and fatty acid synthesis.
Biotin is only bioavailable in nutritionally significant amounts in foods of animal origin, without which it is difficult to guarantee the recommended minimum intake levels. Biotin is absorbed in the intestine and requires complete digestion of all the foods in which it is contained to ensure its bioavailability.
