Description
Description & Mechanism
Vitamin B-12 is a water-soluble, cobalt-containing vitamin essential for fundamental biochemical processes in cellular metabolism. It functions as a cofactor for key enzymatic reactions involved in one-carbon metabolism, nucleic acid synthesis, and mitochondrial energy regulation.
In biochemical and cellular research systems, Vitamin B-12–dependent enzymes such as methionine synthase and methylmalonyl-CoA mutase are studied for their roles in DNA synthesis, amino acid metabolism, and fatty acid processing. Experimental models utilise Vitamin B-12 to investigate cofactor-dependent enzymatic activity, intracellular transport mechanisms, and nutrient–enzyme interactions under controlled conditions.
