Vitamin B7/D-biotin

Cofactor for Carboxylation Reactions
Biotin acts as a coenzyme for five carboxylase enzymes, which are essential for:

• Gluconeogenesis: Synthesizing glucose from non-carbohydrate sources.
• Fatty Acid Synthesis: Involved in the production of fatty acids.
• Amino Acid Metabolism: Important for the metabolism of branched-chain amino acids like leucine, isoleucine, and valine.

Gene Regulation
Biotin influences gene expression by regulating the transcription of genes involved in metabolic pathways and cell signaling.

Skin, Hair, and Nail Health
Biotin is widely known for its role in maintaining healthy hair, skin, and nails by promoting keratin production.

Energy Production
By aiding in the breakdown of macronutrients, biotin supports cellular energy production.

Clinical and Nutritional Uses

• Treating Biotin Deficiency: Biotin supplementation is used to address deficiency symptoms like hair loss, brittle nails, skin rashes, and neurological symptoms.
• Supporting Pregnancy: Increased biotin intake is recommended during pregnancy to support fetal development and prevent congenital disorders.

Cosmetic Industry

• Biotin is a popular ingredient in hair care products, skin creams, and nail health supplements due to its role in promoting keratin production.

Pharmaceutical Applications

• Used in drugs to treat inherited metabolic disorders like biotinidase deficiencyormultiple carboxylase deficiency.

Biotechnology and Research

• Biotin is utilized in biotin-avidin or biotin-streptavidin systems for applications in molecular biology and diagnostics, such as immunoassays.
