▪ Abstract Homocysteine is a sulfur amino acid whose metabolism stands at the intersection of two pathways: remethylation to methionine, which requires folate and vitamin B12 (or betaine in an alternative reaction); and transsulfuration to cystathionine, which requires pyridoxal-5′-phosphate.

Homocysteine and atherothrombosis
Lipids, 2001AbstractAtherosclerosis with or without thrombosis superimposed is the most frequent cause of ischemic heart disease (IHD), peripheral arterial disease, and a main cause of stroke. Conflicting results have been reported in genetic, observational, and experimental studies on the relationship between homocysteine and these atherothrombotic diseases ...

Hyperhomocysteinemia is an independent cardiovascular risk factor that possibly accounts for about one of 5 cardiovascular deaths. It is conceivable that the importance of hyperhomocysteinemia will increase when other risk factors, such as hypertension or hypercholesterolemia, will become less prevalent in the general population.

Homocysteine and Hyperhomocysteinaemia
Current Medicinal Chemistry, 2019Homocysteine (Hcy) is a thiol group containing the amino acid, which naturally occurs in all humans. Hcy is degraded in the body through two metabolic pathways, while a minor part is excreted through kidneys. The chemical reactions that are necessary for degradation of Hcy require the presence of folic acid, vitamins B6 and B12. Consequently, the level

Chronic alcohol consumption can induce alterations in the function and morphology of most if not all brain systems and structures. However, the exact mechanism of brain damage in alcoholics remains unknown. Partial recovery of brain function with abstinence suggests that a proportion of the deficits must be functional in origin (i.e. plastic changes of

Current Opinion in Clinical Nutrition and Metabolic Care, 2000
Hyperhomocysteinaemia has been identified from epidemiological studies as an independent risk factor for cardiovascular disease. Plasma total homocysteine is elevated in renal impairment, which may be a consequence of cardiovascular disease. However, it is also likely that plasma total homocysteine promotes cardiovascular disease, particularly through ...

Homocysteine and atherosclerosis
Current Opinion in Lipidology, 1999Elevated plasma total homocysteine is an independent risk factor for atherosclerotic vascular disease. Risk rises continuously across the spectrum of homocysteine concentrations and may become appreciable at levels greater than 10 mumol/l. A compelling case can be made for screening all individuals with atherosclerotic disease or at high risk.

The aim of this review is to evaluate the evidence for and against fasting plasma total homocysteine (tHcy) as a biomarker/risk factor of impaired reproductive function before and during pregnancy. Apart from nutritional and lifestyle factors, tHcy is also influenced by physiological factors specific to pregnancy such as hemodilution, increased ...

During the past year epidemiological studies have linked elevated plasma total homocysteine concentrations with an increased risk of ischaemic stroke because of arterial disease. Laboratory studies have further explored the mitogenic effects of total homocysteine on vascular smooth muscle, and cytotoxic and thrombophilic effects on vascular endothelium.

Homocysteine and Atherothrombosis
New England Journal of Medicine, 1998In 1969, McCully made the clinical observation linking elevated plasma homocyst(e)ine concentrations with vascular disease.1 He reported autopsy evidence of extensive arterial thrombosis and atherosclerosis in two children with elevated plasma homocyst(e)ine concentrations and homocystinuria.
