It is the largest and most complex vitamin molecule that has been discovered so far, and the only vitamin that contains metal ions. Its crystallization is red, so it is also called red vitamin. Plants do not contain VB12 and cannot make it. Liver is the best source of VB12, followed by milk, meat, eggs, fish, etc. VB12 is an essential coenzyme in the synthesis of RIbonucleic acid and DEoxyribonucleic acid. Deficiency of VB12 can cause pathological changes of the nervous system such as peripheral nerve and central encephalopathy. The archetypal family of natural cobalt coordination compounds, known as corrinoids. The analogue of vitamin B12 differs only in the cobalt beta ligand and is called cobalamin. It's made almost entirely by bacteria. Dietary sources include fish, meat, liver and dairy products; There is little or no cobalamin in plants. Methylcobalamin and cobalamin act as cofactors of enzymes that are converted by the body into their biologically active forms. Severe deficiency can lead to megaloblastic anemia and/or nerve damage Chemicalbook. The discovery of vitamin B12 was first attributed to work in the treatment of a malignant anemia named after Addison, an English physician. In 1926, Minot and Murphy discovered that it could be cured by ingestion of large amounts of raw liver, for which they won the 1934 Nobel Prize in Physiology and Medicine. Following Minot and Murphy's discovery, this malignant anaemia was successfully cured with liver concentrate. In 1948, Riches of The United States and Smith and Parker of the United Kingdom respectively extracted liver concentrate.
