Homocysteine Metabolism in Health and Disease

Abstract

Changes in methyl group metabolism and homocysteine balance have been implicated in various clinical disorders in recent decades. Elevated circulating homocysteine concentrations are linked to various dietary, hormonal, and genetic variables, cancer development, and autoimmunity. Here in this chapter, we have explained detailed links about homocysteine and cancer. Homocysteine is a sulfur-containing amino acid that is metabolized via one of the two pathways: remethylation or transsulfuration. It is produced from the metabolism of methionine, an essential amino acid. Abnormalities cause hyperhomocysteinemia in this mechanism. It is linked to a higher risk of vascular and neurological illnesses, auto immunological disorders, birth abnormalities, diabetes, renal disease, osteoporosis, neuropsychiatric disorders, and cancer. Hcy appears to be a vital predictor of overall health condition, according to a wealth of evidence. Recent research has begun to uncover the cellular and molecular pathways through which folate prevents age-related illness. Even though much remains to be learned, our understanding of the relationship between disease, methyl balance, and epigenetic control of gene expression has continuously progressed. However, the role of homocysteine balance in health and disease seems to be well known.
