Biotin Metabolism Service

Overview

Biotin (Vitamin B7) is a vitamin essential for the maintenance of normal physiological functions in the animal organism. It plays an important role in the metabolism of glucose, amino acids and fatty acids in mammals as a component of four carboxylase coenzymes. There are five biotin-dependent carboxylases: methylcrotonyl-CoA carboxylase, pyruvate carboxylase, propionyl-CoA carboxylase and two forms of acetyl-CoA carboxylase. These enzymes catalyse key carboxylation reactions in gluconeogenesis, fatty acid metabolism and amino acid catabolism. Thus, biotin plays an essential role in maintaining metabolic homeostasis. Mammals cannot synthesize biotin in vivo and therefore must obtain it from material synthesized by intestinal microflora and from dietary sources. Two principal pathways of biotin catabolism have been identified in mammals (Figure 1). In the first pathway, the valeric acid side chain of biotin is degraded by β-oxidation. β-Oxidation of biotin leads to the formation of bisnorbiotin, tetranorbiotin, and related intermediates that are known to result from β-oxidation of fatty acids. The cellular site of this β-oxidation of biotin is uncertain. Spontaneous decarboxylation of the unstable β-keto acids causes formation of bisnorbiotin methyl ketone and tetranorbiotin methyl ketone. The aberrant biotin metabolism is closely connected to various human diseases.

Creative Proteomics has the LC-MS technology platform to provide you with qualitative and quantitative biotin analysis to accelerate your project.
