Background Although humans require dietary choline for methyl donation, membrane function, and neurotransmission, choline can also be derived from the de novo synthesis of phosphatidylcholine, which is up-regulated by estrogen. A recommended Adequate

We have previously reported that folate and choline metabolism are interrelated. Total folate concentration was significantly diminished (31%) when rats were fed a choline-deficient diet for 2 weeks. Distribution among species of folates (differing i

We have developed a method for measuring dimethylamine (DMA), trimethylamine (TMA), and trimethylamine N-oxide (TMAO) in biological samples using gas chromatography with mass spectrometric detection. DMA, TMA, and TMAO were extracted from biological

Choline deficiency and treatment with methotrexate (MTX) both are associated with fatty infiltration of the liver. Choline, methionine, and folate metabolism are interrelated and converge at the regeneration of methionine from homocysteine. MTX pertu

We have developed a reproducible and sensitive procedure for the isolation and measurement of choline, phosphocholine, glycerophosphocholine, phosphatidylcholine, lysophosphatidylcholine and acetylcholine in a single 100-mg sample of biological tissu

Dimethylamine is important because it is a precursor of nitrosodimethylamine, a suspected carcinogen in man. Significant quantities of dimethylamine and nitrite are found in gastric fluid, and conditions in the stomach are favorable for nitrosodimeth

Trimethylamine (TMA) and dimethylamine (DMA) are normal components of human urine and are precursors of dimethylnitrosamine, a potent carcinogen. In part, DMA and TMA are products of the metabolism of dietary choline by intestinal bacteria. Most TMA
An understanding of the biosynthesis and metabolism of dimethylamine (DMA) is important because it is a precursor of dimethylnitrosamine (nitroso-DMA). DMA is the major short-chain aliphatic amine in human and rat urine. DMA is formed from trimethyla
