维生素B12

Vitamin B12

维生素B12,维生素B12或维生素B-12(也称为钴胺素)是一种水溶性维生素,在大脑和神经系统的正常功能以及形成血液中具有关键作用。 它是八种维生素B之一。 它通常参与人体各细胞的代谢,特别是影响DNA合成和调节,而且还涉及脂肪酸的合成和能量产生。 真菌,植物和动物都不能生产维生素B12。 只有细菌和古细菌具有合成所需的酶,尽管由于细菌共生,许多食物是B12的天然来源。 维生素是最大和最结构复杂的维生素,只能通过细菌发酵合成才能在工业上生产。 维生素B12由一类化学相关的化合物组成,所有这些都具有维生素的活性。 它包含位于平面四吡咯环中心的称为Corrin环的生化稀有元素钴。 Vitamin B12, vitamin B12 or vitamin B-12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins. It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid synthesis and energy production. Neither fungi, plants, nor animals are capable of producing vitamin B12. Only bacteria and archaea have the enzymes required for its synthesis, although many foods are a natural source of B12 because of bacterial symbiosis. The vitamin is the largest and most structurally complicated vitamin and can be produced industrially only through bacterial fermentation-synthesis. Vitamin B12 consists of a class of chemically related compounds, all of which have vitamin activity. It contains the biochemically rare element cobalt sitting in the center of planar tetra-pyrrole ring called a Corrin ring.
