Introduction of Vitamin B12
Vitamin B12, also known as cobalamin, is the only vitamin containing metal elements. Vitamin B12 is a red crystalline powder, odorless and tasteless, slightly soluble in water and ethanol, most stable in weak acid conditions with a pH value of 4.5 to 5.0, decomposed in strong acids (pH<2) or alkaline solutions, and can be destroyed to a certain extent when heated . Higher animals and plants cannot produce vitamin B12, and vitamin B12 in nature is synthesized by microorganisms. Vitamin B12 is the only vitamin that requires the help of an intestinal secretion (endogenous factor) to be absorbed. It participates in the manufacture of bone marrow red blood cells, prevents pernicious anemia, and prevents brain nerves from being damaged.
