[PAR] [TLE] David Ballou [SEP] David P. Ballou is a professor of biological chemistry at the University of Michigan Medical School in the United States.  He is best known for his development of rapid-reaction techniques, including stopped flow and rapid freeze-quench EPR methods, as tools to study the mechanisms of enzymes containing flavin, iron, cobalamin, or pyridoxal phosphate cofactors.  Many of these studies were performed in collaboration with other scientists, most often with colleagues at Michigan. [PAR] [TLE] Vitamin B12 [SEP] Vitamin B, also called cobalamin, is a water-soluble vitamin that has a key role in the normal functioning of the brain and nervous system via the synthesis of myelin (myelinogenesis), and the formation of red blood cells.  It is one of eight B vitamins.  It is involved in the metabolism of every cell of the human body, especially affecting DNA synthesis, fatty acid and amino acid metabolism.  No fungi, plants, or animals (including humans) are capable of producing vitamin B. Only bacteria and archaea have the enzymes needed for its synthesis.  Some substantial sources of B include animal products (shellfish, meat), fortified food products, and dietary supplements. B is the largest and most structurally complicated vitamin and can be produced industrially through bacterial fermentation synthesis, typically used to manufacture B for fortified foods and supplements.  It can also be produced synthetically via vitamin B total synthesis.
