The fates and the rates of metabolism of acetate, trimethylamine, methylamine, and methanol were examined to determine the significance of these compounds as in situ methane precursors in surface sediments of an intertidal zone in Maine. Concentrations of these potential methane precursors were generally <3 muM, with the exception of sediments containing fragments of the seaweed Ascophyllum nod...

The trimethylamine content of most marine fish, especially the gadoid species, is internationally accepted as an index ofspoilage. However, ammonia, dimethylamine, and other aminesalso contribute to the trimethylamine value. Variations in the conditions of the three current methods used to analyze for trimethylamine content were studied in detail to determine the best condition to extract trime...

The response of methanogenesis and sulfate reduction to trimethylamine, choline, and glycine betaine was examined in surface sediments from the intertidal region of Lowes Cove, Maine. Addition of these substrates markedly stimulated methanogenesis in the presence of active sulfate reduction, whereas addition of other substrates, including glucose, acetate, and glycine, had no effect on methane ...

The excretion of aliphatic amines, methylamine, dimethylamine and trimethylamine in the urine and faeces of rats fed on a control diet and diets supplemented with creatinine, lecithin or choline were measured over a 14 d feeding period. The rats were then killed and concentrations of amines in small and large intestinal contents measured. Adding creatinine to the diet resulted in a significant ...

Four variants of the methods for obtaining and conditions synthesis choline chloride were analyzed: all use trimethylamine mild

Methanomassiliicoccales are less-known members of the human gut archaeome. Members this order use methylated amines, including trimethylamine, in methane production.
