Biotin cofactor
WebBiotin is a cofactor for carboxylase enzymes. There are five human enzymes for which biotin is a coenzyme: acetyl-CoA carboxylase I (soluble cytoplasm), acetyl-CoA carboxylase II (mitochondrial fatty acid oxidation), pyruvate carboxylase, methylcrotonyl-CoA carboxylase, and propionyl-CoA carboxylase. Acetyl-CoA carboxylase II … Biotin is a coenzyme for five carboxylase enzymes, which are involved in the catabolism of amino acids and fatty acids, synthesis of fatty acids, and gluconeogenesis.
