(Redirected from Methylcobalamin)
Vitamin B12, also known as cobalamin, is a water-soluble vitamin, one of the B vitamins. Forms of cobalamin include hydroxo-cobalamin, cyano-cobalamin, methyl-cobalamin, and adenosyl-cobalamin.
Physiology[edit | edit source]
B12 is involved in cellular metabolism and formation of red blood cells (RBCs). It has an integral role in brain and nervous system function. Absorption of B12 from dietary sources requires an intrinsic factor (IF or GIF), i.e., a glycoprotein, synthesized in and secreted from parietal cells in the lining of the human stomach.
Immune system[edit | edit source]
Vitamin B12 deficiency may be associated with decreased natural killer cell activity.[1]
