Vitamin B7, commonly known as biotin, is a water-soluble vitamin that is part of the B-complex group. It plays a crucial role in various metabolic processes in the human body, primarily as a coenzyme for carboxylase enzymes. These enzymes are involved in the metabolism of carbohydrates, fats, and proteins.
Biotin is essential for gluconeogenesis (the synthesis of glucose from non-carbohydrate sources), fatty acid synthesis, and the breakdown of certain amino acids. Because it is water-soluble, biotin is not stored in the body to a significant extent, and regular dietary intake is necessary. It can be obtained from a variety of foods, including egg yolks, nuts, seeds, sweet potatoes, and organ meats. The gut microbiota can also synthesize some biotin, though the extent of its absorption and contribution to human nutrition is still an area of research (NIH ODS).
