Vitamin B12, also known as cobalamin, is a polycyclic compound containing trivalent cobalt. Four reduced pyrrole rings are linked together to form a corrin macrocycle (similar to porphyrin), the only metal-containing combination—elemental vitamins. Vitamin B12 is a red crystalline powder, odorless and tasteless, slightly soluble in water and ethanol, the most stable under the condition of pH 4.5-5.0 weak acid, decomposed in strong acid (pH<2) or alkaline solution, it can be destroyed to a certain extent when heated. Higher animals and plants cannot manufacture vitamin B12, and microorganisms synthesize vitamin B12 in nature. Vitamin B12 is the only vitamin that requires the help of an intestinal secretion (endogenous factor) to be absorbed, participates in the production of bone marrow red blood cells, prevents pernicious anemia, and prevents damage to the nerves in the brain.
