If you were deficient in vitamins B₆ and B₁₂ and had high blood levels of homocysteine,what dietary substance could remove some of the homocysteine by donating a methyl group to form methionine?

Question

Quizplus · Accepted Answer

Betaine is a dietary substance that can donate a methyl group to homocysteine to form methionine, therefore reducing high blood levels of homocysteine. Vitamins B₆ and B₁₂ are also important for the conversion of homocysteine to methionine, but the given options only include a dietary substance. Biotin, serine, and creatine do not have a significant role in the methionine cycle or homocysteine metabolism.
