Question
Vitamins $\mathrm{B}_{6}, \mathrm{B}_{12},$ and folate may be recommended for individuals with high blood serum levels of homocysteine (a condition called hyperhomocysteinemia). How might these vitamins ameliorate hyperhomocysteinemia?
Step 1
This is why folate (vitamin B9) might help alleviate the symptoms of hyperhomocysteinemia. Mathematically, this can be represented as: \[ \text{Homocysteine} + \text{Folate-derived compounds} \rightarrow \text{Methionine} \] Show more…

Deficiency of which of the following vitamins leads to high levels of homocysteine in the blood?'
Vitamins B6, B12, and folate are involved in the metabolism of the amino acid homocysteine. Select the statement that correctly describes the relationship between B-vitamins and homocysteine. a. Excessive intake of vitamin B12 leads to elevated levels of homocysteine in the blood. b. Adequate intake of vitamin B6 allows for the conversion of homocysteine to methionine. c. Deficiency of vitamin B6 can result in elevated levels of homocysteine in the blood. d. Low levels of homocysteine increase the risk for cardiovascular disease.
Vitamin $\mathrm{B}_{12}$ deficiency can arise from a few rare genetic diseases that lead to low $\mathrm{B}_{12}$ levels despite a normal diet that includes $\mathrm{B}_{12}$ -rich meat and dairy sources. These conditions cannot be treated with dietary $\mathrm{B}_{12}$ supplements. Explain.
