| | Trimethylamine N-oxide Usage And Synthesis |
| Description | Trimethylamine N-oxide (TMAO) is a metabolite of choline, phosphatidylcholine, and L-carnitine . It is formed by gut microbiota-mediated metabolism of choline, phosphatidylcholine, and L-carnitine to TMA followed by oxidation of TMA by flavin-containing monooxygenase 3 (FMO3) in the liver. Dietary administration of TMAO (0.12% w/w) increases renal tubulointerstitial fibrosis, collagen deposition, and Smad3 phosphorylation in mice and increases aortic lesion area in atherosclerosis-prone ApoE-/- mice. Plasma levels of TMAO are elevated in patients with chronic kidney disease and decreased in patients with active, compared with inactive, ulcerative colitis. Elevated plasma levels of TMAO are associated with increased risk of cardiovascular disease. | | Chemical Properties | Colorless to yellow solid; odorless. | | Chemical Properties | White crystalline powder | | Uses | TrimethylamineN-oxide can be used:
- As a demetallationand decarbonylationreagent for organometallic compounds.
- To prepare azomethine ylide by reaction with lithium di-isopropylamide. This, in turn, may be reacted with simple alkenes to obtain corresponding pyrrolidines.
- To mediate the conversion of thiols to disulfides.
