Vitamin B12 (cobalamin)

Product Details

Vitamin B12 is a class of porphyrinoid compounds containing a porphyrin ring, and cobalamin is a common name for vitamin B12. The porphyrin ring formed by the four reduced pyrrole rings in the vitamin B12 molecule is the core of the vitamin B12 molecule.  

Vitamin B12, which is found in nature, is synthesized by bacteria and is not present in plants unless it is contaminated with microorganisms. Vitamin B12 in food is mainly present in the form of methylcobalamin and coenzyme vitamin B12, and both bind to proteins. The human body cannot synthesize vitamin B12, mainly relying on animal foods. The vitamin B12 is rich in liver and kidney tissues, meat, eggs and dairy products.

Vitamin B12, also known as cobalamin, is the only vitamin-containing vitamin with important physiological functions. As a cofactor of methyltransferase, vitamin B12 is involved in the synthesis of proteins and amino acids in the body, ensuring the normal development of infants and young children. In addition, it also protects the transfer and storage of folic acid in cells, and is an indispensable vitamin for the nervous system.
