Trimethylamine and Foetor Hepaticus
Scandinavian Journal of Gastroenterology, 1999In patients with various degrees of hepatocellular failure and portosystemic shunting of blood, the breath may acquire a sweet, musty, or even slightly faecal aroma, termed foetor hepaticus, which has been attributed mainly to volatile sulphur compounds with contributions from various nitrogenous substances.

A spectrophotometric trimethylamine monooxygenase assay
Proteins: Structure, Function, and Bioinformatics, 2023AbstractTrimethylamine monooxygenase (Tmm, EC‐1.14.13.148) belongs to the family of flavin‐containing monooxygenases that oxidize trimethylamine into trimethylamine‐N‐oxide (TMAO). Conventional methods for assaying Tmm are accurate over a narrow range of substrate/product concentrations.

Trimethylamine and odorous sweat
Journal of Inherited Metabolic Disease, 2003AbstractAnalysis of sweat collected from patients experiencing ichthyohidriosis, and from volunteers in whom this odour phenomenon had been artificially induced, showed that trimethylamine was the major causative factor.

1. The sensory qualities of "crabby", "fishy" tainted eggs are closely similar to those of an aqueous solution of trimethylamine (1 x 10(-2) microgram/g). 2. The odour threshold of trimethylamine in water is 5 +/- 1 x 10(-4) microgram/g. 3. The taint occurs in eggs which contain more than 0.8 microgram/g trimethylamine.

The Bacterial Reduction of Trimethylamine Oxide to Trimethylamine
Journal of the Fisheries Research Board of Canada, 1939Only three of thirty microorganisms isolated from seven samples of fresh or lightly smoked sea fish muscle in various stages of decomposition reduced trimethylamine oxide to trimethylamine. This reduction is due to an enzyme, which activates trimethylamine oxide rendering it susceptible to reduction by many of the dehydrogenases of the bacterial cell.

The Fate of Trimethylamine Oxide and Trimethylamine in Man
Journal of the Fisheries Research Board of Canada, 1941Normal human urine contains small amounts of trimethylamine oxide but no appreciable trimethylamine. Trimethylamine when administered orally appears mainly as trimethylamine oxide in the urine; trimethylamine oxide similarly administered is excreted unchanged, thus proving the existence in man of a system capable of oxidizing trimethylamine.
