We leverage our rich experience, professional expertise, and advanced technologies to speed up your scientific purposes of biotin metabolism analysis in animal.


Biotin is a vitamin that is an essential nutrient for animals. As a cofactor for enzymes involved in carboxylation reactions, 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. Scientists at Creative Proteomics take advantage of highly quantitative methods with high-performance liquid chromatography (HPLC) for the determination of biotin metabolism related metabolites levels in various samples. Furthermore, we provide reliable, rapid and cost-effective biotin metabolism related service to speed up your research aims ranging from diseases diagnosis to gaining new insights in disease mechanism or treatment.
