Significance and sources of biotin
Domina Petric, MD
• A key feature of biotin metabolism is that
it is recycled by proteolytic cleavage from
the four biotinyl carboxylases by the
enzyme biotinidase.
• This recycling, and the prevalent hind gut
microbial synthesis of the vitamin, allow
quantitative dietary requirements for
biotin to be relatively small.

Significance
Most foods contain the vitamin
as free biotin and as biocytin.
Biocytin is biotin covalently
bound to protein lysyl residues.

...
Biotin is unstable to oxidizing conditions and is
destroyed by heat, especially under conditions
that support simultaneous lipid peroxidation.
Such processing techniques as the canning of foods
can result in substantial losses of biotin.
These losses can be reduced by the use of an
antioxidant: vitamin C, vitamin E, butylated
hydroxytoluene [BHT], butylated hydroxyanisole [BHA].

10
Stability
Total fecal excretion of biotin exceeds the
amount consumed in the diet.
This is due to the biosynthesis of significant
amounts of biotin by the microflora of the
proximal colon.

Significance and sources of biotin

  • 1. Significance and sources of biotin Domina Petric, MD
  • 2. • A key feature of biotin metabolism is that it is recycled by proteolytic cleavage from the four biotinyl carboxylases by the enzyme biotinidase. • This recycling, and the prevalent hind gut microbial synthesis of the vitamin, allow quantitative dietary requirements for biotin to be relatively small. April 18, 2018 Combs GF. The Vitamins. Fundamental Aspects in Nutrition and Health. Elsevier Inc. 2008. 2 Significance
  • 3. Most foods contain the vitamin as free biotin and as biocytin. Biocytin is biotin covalently bound to protein lysyl residues. April 18, 2018 Combs GF. The Vitamins. Fundamental Aspects in Nutrition and Health. Elsevier Inc. 2008. 3 Distribution in foods

  • 10. Biotin is unstable to oxidizing conditions and is destroyed by heat, especially under conditions that support simultaneous lipid peroxidation. Such processing techniques as the canning of foods can result in substantial losses of biotin. These losses can be reduced by the use of an antioxidant: vitamin C, vitamin E, butylated hydroxytoluene [BHT], butylated hydroxyanisole [BHA]. April 18, 2018 Combs GF. The Vitamins. Fundamental Aspects in Nutrition and Health. Elsevier Inc. 2008. 10 Stability
  • 11. Total fecal excretion of biotin exceeds the amount consumed in the diet. This is due to the biosynthesis of significant amounts of biotin by the microflora of the proximal colon.
