Background:
Trimethylamine-d9N-oxide is intended for use as an internal standard for the quantification of trimethylamine N-oxide by GC- or LC-MS. Trimethylamine N-oxide (TMAO) is a metabolite of choline, phosphatidylcholine, and L-carnitine .1It 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.1,2,3Dietary 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-proneApoE-/-mice.1,4Plasma levels of TMAO are elevated in patients with chronic kidney disease and decreased in patients with active, compared with inactive, ulcerative colitis.1,2Elevated plasma levels of TMAO are associated with increased risk of cardiovascular disease.4
