Description

Description générale

Vitamin B₁₂ is a water-soluble vitamin present in dietary sources including milk products, eggs, fish and meat. Vitamin B₁₂, also called as cyanocobalamin, binds to protein transcobalamins. Structurally vitamin B₁₂ has two pyrrole rings. The two forms comprise methylcobalamin or 5-deoxyadenosyl cobalamin, which are bioavailable.

Actions biochimiques/physiologiques

Vitamin B₁₂ plays a key role in DNA synthesis and methylation proteins. The intrinsic factor is essential for its circulation and reabsorption. Vitamin B₁₂ coordinates with folic acid in the synthesis of red blood cells as well as in maintaining iron levels. It is essential for cellular energy production and serves as a cofactor for L-methyl malonyl-CoA mutase and methionine synthase. Vitamin B₁₂ deficiency leads to pernicious anemia, megaloblastic anemia and neural tube defects.
