carboxylases

Biotin (Vitamin H) is a water-soluble B-vitamin and is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids.

(+)-Biotin 4-amidobenzoic acid is a substrate of biotinidase, which cleaves biotin amide to give biotin in vivo. Biotin is an essential coenzyme for certain carboxylases and is used to modify histones and regulate gene transcription. Biotinidase has key roles in intestinal absorption of biotin, the transport of biotin in plasma, and in the regulation of histone biotinylation. (+)-Biotin 4-amidobenzoic acid is hydrolyzed by biotinidase to release 4-aminobenzoic acid (PABA), which can be quantified by either fluorescent or colorimetric methods. This approach is used in biotinidase activity assays in newborn screening protocols to evaluate biotinidase deficiency.

Biotin Sodium (Vitamin B7) is a water-soluble B vitamin acting as a coenzyme for five carboxylases critical in human metabolism, including the synthesis of fatty acids, isoleucine, and valine, as well as gluconeogenesis. It is essential for cell growth, fatty acid production, and the metabolism of fats and amino acids [1] [2] [3].
