الوصف
Biotin, an essential water-soluble vitamin, Also known as Vitamin B8, is the coenzyme for five carboxylases in humans. These carboxylases are involved in amino acid catabolism, fatty acid synthesis and gluconeogenesis. In its action as a coenzyme, biotin becomes covalently attached to these carboxylases. Symptoms associated with biotin deficiency include, scaly dermatitis, pallor, irritability, anorexia, nausea and hair loss. In addition, altered immune status may occur as a result of biotin deficiency. See Also Biotinidase, Quantitative, Serum
