BIOTIN METABOLISM IN PLANTS Annual Review of Plant Biology

Biotin, synthesized in plants, is essential to plant growth and development. Bacteria also synthesize biotin, and it is thought that bacteria resident in the large intestine may synthesize biotin that is absorbed and utilized by the host organism. Synthesis starts from two precursors, alanine and pimeloyl-CoA. These form … See more Biotin (or vitamin B7) is one of the B vitamins. It is involved in a wide range of metabolic processes, both in humans and in other organisms, primarily related to the utilization of fats, carbohydrates, and amino acids. The … See more Biotin is classified as a heterocyclic compound, with a sulfur-containing ring fused ureido and tetrahydrothiophene group. A C5 … See more Biotin is a water-soluble B vitamin. Consumption of large amounts as a dietary supplement results in absorption, followed by excretion into urine as biotin. Consumption of … See more Primary biotin deficiency, meaning deficiency as a consequence of too little biotin in the diet, is rare, because biotin is contained in so many foods. Subclinical deficiency can … See more The US National Academy of Medicine updated Dietary Reference Intakes for many vitamins in 1998. At that time there was insufficient information to establish estimated average … See more The enzyme holocarboxylase synthetase covalently attaches biotin to five human carboxylase enzymes: • Acetyl-CoA carboxylase alpha (ACC1) • Acetyl-CoA carboxylase beta (ACC2) • Pyruvate carboxylase (PC) See more Chemically modified versions of biotin are widely used throughout the biotechnology industry to isolate proteins and non-protein compounds for … See more WebBiotin is an enzyme cofactor indispensable to metabolic fixation of carbon dioxide in all three domains of life.
