Question

Quizplus · Accepted Answer

The conversion of homocysteine to methionine with the simultaneous conversion of methyl vitamin B12 to vitamin B12 is an example of single carbon metabolism. Single carbon metabolism involves the transfer of one-carbon units between molecules, such as methyl groups or formyl groups, and is important in processes such as DNA synthesis, amino acid metabolism, and neurotransmitter synthesis. In this example, the transfer of a methyl group from methyl vitamin B12 to homocysteine results in the formation of methionine and vitamin B12.
