But as vitamin B12 is not found naturally in foods such as fruit, vegetables and grains, vegans may not get enough of it.}
The discussion speculated that this could be an indirect consequence of improved hoof health or a direct effect on milk production. The proposed mechanisms are that biotin activates acetyl-CoA carboxylase, a key rate-limiting enzyme during the synthesis of myelin, and by reducing axonal hypoxia through enhanced energy production. The hypothesis is that biotin may promote remyelination of the myelin sheath of nerve cells, slowing or even reversing neurodegeneration. The initial step was described as a condensation of pimelyl-CoA and alanine to form 7-oxo-8-aminopelargonic acid. Gyorgy continued his work on biotin and in 1941 published a paper demonstrating that egg-white injury was caused by the binding of biotin by avidin. The name biotin derives from the Greek word bios (‘to live’) and the suffix “-in” (a general chemical suffix used in organic chemistry).

Neonatal screening for biotinidase deficiency started in the United States in 1984, with many countries now also testing for this genetic disorder at birth. For the first two, biotin serves as a cofactor responsible for the transfer of bicarbonate to acetyl-CoA, converting it to malonyl-CoA for fatty acid synthesis. Urine content is proportionally about half biotin, plus bisnorbiotin, biotin sulfoxide, and small amounts of other metabolites.
While symptomatic biotin deficiency is rare, low biotin levels are common during pregnancy. Many hair products that claim to encourage healthier, stronger hair contain biotin. The body does not store water-soluble vitamins, so people need to absorb them from their diets.

Since it is water-soluble, excess amounts are not stored in the body and are instead flushed out through the urine. Moreover, so far no research has shown the possibility of overdosing on vitamin B7. Some amount of vitamin B7 can also be synthesized by the bacteria living in the gut. Since biotin is an important factor in the synthesis of glucose, it may help maintain an appropriate blood sugar level in patients suffering from type 2 diabetes. It is suggested that biotin aids cell growth and the maintenance of mucous membranes. It acts as a coenzyme in a number of metabolic pathways involving fatty acids and essential amino acids, as well as in gluconeogenesis – the synthesis of glucose from non-carbohydrates.
