Its growth rate is proportional to the amount of cobalamin in the growth medium. However, lactis has been demonstrated to have the option to utilize pseudocobalamin, which is inactive for humans, [2] as well as "alkali-resistant factors" (deoxyribosides and deoxynucleotides), [1] leading to an overestimation of the amount of cobalamine in food.
Intrinsic factor (IF), cobalamin binding intrinsic factor, [5] also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells (in humans) or chief cells (in rodents) of the stomach. It is necessary for the absorption of vitamin B 12 later on in the distal ileum of the small intestine. [6]

TC-2 binds cobalamin once it has been taken up by enterocytes of the terminal ileum and the "Intrinsic Factor-Vitamin B12" complex has been degraded. TC-2 is then involved with the transport of Vitamin B12 to the tissues, where it binds to its plasma membrane receptor (TC-2R), a heavily glycosylated protein with a monomeric molecular mass of 62 ...
