This finding was also observed in biopsy samples from patients with ulcerative colitis, suggesting a shared pathway. “This raises the possibility that [the biotin transport pathway] could be a target for therapy,” the investigators wrote. WebBiotin, also known as vitamin B7 or vitamin H, is an essential vitamin because it acts as a cofactor for five biotin-dependent carboxylases that play critical roles in the intermediate metabolism of gluconeogenesis, fatty acid synthesis, and amino acid catabolism. 1 Pharmacology and pathophysiology of biotin have been discussed in Chapter 2.
