BACKGROUND. Healthy people can have low levels of cobalamin (vitamin B12) without symptoms or signs of cobalamin deficiency. Early detection of deficiency is imperative for treatment to be effective. Development…
Folate and vitamin B12 are required both in the methylation of homocysteine to methionine and in the synthesis of S-adenosylmethionine. S-adenosylmethionine is involved in numerous methylation reactions involving proteins, phospholipids,…
Homocysteine, an atherogenic amino acid, is either remethylated to methionine or metabolized to cysteine by the transsulfuration pathway. The biochemical conversion of homocysteine to cysteine is dependent upon two consecutive,…
