WebHomocysteine is an amino acid made in the body through metabolism of the essential amino acid methionine. In healthy circumstances, homocysteine is rapidly broken down, but genetic factors, nutritional inadequacies, certain medications, and some medical conditions can lead to excess homocysteine accumulation, which can damage blood vessels. 1 High … WebJan 1, 2005 · Methods. We studied the effect of 3 weeks of oral treatment with 5 mg folic acid per day on homocysteine metabolism in six chronic hemodialysis patients and six healthy controls.Primed, continuous infusions with [2 H 3-methyl-1-13 C] methionine were used to determine flux rates of methionine transmethylation, homocysteine remethylation, …
