Biotin origin
Did you know?
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 name biotin, borrowed from the German Biotin, derives from the Ancient Greek word βίοτος … See more Biotin is classified as a heterocyclic compound, with a sulfur-containing ring fused ureido and tetrahydrothiophene group. A C5-carboxylic acid side chain is appended to one of the rings. The ureido ring, containing the … See more The US National Academy of Medicine updated Dietary Reference Intakes for many vitamins in 1998.

Bacteria also synthesize biotin, and it is thought that bacteria … 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 … See more WebBiotin also works as a cofactor of carboxylating enzymes, such as pyruvate carboxylase. It catalyzes the formation of oxaloacetate from pyruvate and CO 2. Biotin conjugation with avidin or streptavidin helps in linking the target molecule (antibody, nucleotide, protein A etc.) with the labeling system (enzyme, fluorescent, chemiluminescent probes).
