Regular cigarette smoking influences the transsulfuration pathway, endothelial function, and inflammation biomarkers in a sex-gender specific manner in healthy young humans.
Folic acid and vitamin B12 detoxify homocysteine via the "methylation" (24) pathway, whereas vitamin B6 detoxifies homocysteine via the "transsulfuration" (25) pathway.
It is normally converted into other amino acids for the body to use through the processes of transsulfuration and methylation, which spurs the activities of the cardiovascular, neurologic, reproductive, and detoxification systems.
The authors showed that there is a conversion of MHA into L-Met in the small intestines of chickens and MHA provides higher cysteine concentrations in relation to DLM, suggesting that MHA is preferably shifted through the transsulfuration route and subsequent formation of sulfate ions.
In this study, metabolites of the folate-dependent transmethylation and transsulfuration biochemical pathways of pregnant mothers were measured to determine whether or not the risk of having a child with autism could be predicted by her metabolic profile.
In the study, led by Juergen Hahn, Professor at Rensselaer Polytechnic Institute in New York, metabolites of the folate-dependent transmethylation and transsulfuration biochemical pathways of pregnant mothers were measured to determine whether or not the risk of having a child with autism could be predicted by her metabolic profile.
In the study, led by Juergen Hahn, Professor at Rensselaer Polytechnic Institute in New York, metabolites of the folate-dependent transmethylation and transsulfuration biochemical pathways of pregnant women were measured to determine whether the risk of having a child with autism could be predicted by her metabolic profile.
cruzi appears to be the first protist proven to have two independent pathways for cysteine production; sulfur-assimilation from sulfate and transsulfuration from methionine via cystathionine.
These abnormalities were attributed to low vitamin B6 levels [7] and alteration in either the transsulfuration pathway or the regulation of the homocysteine cycle [24].
Homocysteine, as the intersection of the methylation, remethylation and transsulfuration pathways, is an important component in the one-carbon metabolism.
Hcy levels are regulated by vitamin [B.sub.12]- and folate-dependent remethylation to Met, catalyzed by Met synthase (with methyltetrahydrofolate cofactor provided by the MTHFR enzyme) and betaine-Hcy methyltransferase, as well as by vitamin B6-dependent transsulfuration to cysteine, the first step of which is catalyzed by cystathionine [beta]-synthase (CBS).
4-Pyridoxic acid, the catabolic product of vitamin B6, regulates transsulfuration reactions for glutathione production and aberrant vitamin B-dependent hepatic methionine metabolism [47].
