WebMay 17, 2024 · Other enzymes contain a nonprotein component called a cofactor that is necessary for the enzyme’s proper functioning. This cofactor is usually weakly bonded to the polypeptide chains through intermolecular interactions. There are two types of cofactors: inorganic ions [e.g., zinc or Cu (I) ions, also known as minerals] and organic … WebBiotin, also known as vitamin B 7 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.The …

WebDec 9, 2016 · Organic cofactors are mainly derived from vitamins such as thiamine, riboflavin, biotin or niacin but there are also non-vitamin cofactors such as coenzyme Q 10 or heme. The group of inorganic cofactors comprises metal ions such as iron, magnesium, copper, zinc, and molybdenum. WebBiotin is an essential cofactor for enzymes present in key metabolic pathways such as fatty acid biosynthesis, replenishment of the tricarboxylic acid cycle, and amino acid metabolism. Biotin is synthesized de novo in microorganisms, plants, and fungi, but this metabolic activity is absent in mammals, making biotin biosynthesis an attractive ...
