Principal Sources in FoodPrincipal dietary sources of biotin include:
Biotin in the BodyBiotin, like many other vitamins in the B-complex, is required for cellular metabolism of carbohydrate, fat and protein. It is also involved in the production of amino acids and glucose, and in the catalysis of fatty acid synthesis.
Deficiency is rare, but can result in:
StabilityBiotin is quite stable to heat and most of the cooking losses are due to biotin leaching into the cooking water.
SynthesisThe chemical synthesis of biotin, using fumaric acid as a starting material, was developed by Goldberg and Sternbach in 1949.
