Trimethylamine N-oxide synthesis: A human variant

Biochemical Medicine, 1972
Abstract A 6-year-old girl exhibiting a variety of clinical symptoms including an apparant inability to metabolize trimethylamine has been shown to possess a defective liver trimethylamine oxidizing system. The defect manifested itself in a Km for trimethylamine which was five times that characteristic of normal enzyme preparation.

Trimethylamine N-Oxide (TMAO) as a Biomarker

2022
The interaction between diet, microbiome, and noncommunicable disease onset is gaining growing attention. The trimethylamine N-oxide (TMAO) is a gut microbiota derivative that has been suggested as a potential regulator of human health, especially (but not exclusively) for its association with cardiovascular diseases. It derives from the trimethylamine

Trimethylamine N-Oxide in Aquatic Foods

Journal of Agricultural and Food Chemistry
Trimethylamine N-oxide (TMAO), a characteristic nonprotein nitrogen compound, is widely present in seafood, which exhibits osmoregulatory effects for marine organisms in vivo and plays an important role in aquaculture and aquatic product preservation. However, much attention has been focused on the negative effect of TMAO since it has recently emerged ...

Microbial Dimethylsulfoxide and Trimethylamine-N-Oxide Respiration

2005
Over the last two decades, the biochemistry and genetics of dimethylsulfoxide (DMSO) and trimethylamine-N-oxide (TMAO) respiration has been characterised, particularly in Escherichia coli marine bacteria of the genus Shewanella and the purple phototrophic bacteria, Rhodobacter sphaeroides and R. capsulatus.

A comparative study of trimethylamine-N-oxide biosynthesis

Biochimica et Biophysica Acta, 1963
A broad spectrum of species of plants and animals have been examined for their ability to convert trimethylamine to its N-oxide. Of the animal species studied, and under the conditions used in this investigation, trimethylamine-N-oxide synthesis from trimethylamine seems generally to be restricted to the vertebrates.

Trimethylamine-N-oxide

Current Opinion in Lipidology, 2016
This article evaluates the link between trimethylamine-N-oxide (TMAO) and bile acids and the consequent impact on the development of atherosclerosis.Elevation in plasma TMAO concentrations is associated with an increased risk of cardiovascular disease in many different patient cohorts.

Trimethylamine N-oxide impairs perfusion recovery after hindlimb ischemia

Biochemical and Biophysical Research Communications, 2020
The circulating level of trimethylamine N-oxide (TMAO) has been reported to be associated with the prognosis of of peripheral arterial disease (PAD) patients. However, the effects of TMAO on neovascularization and perfusion recovery after PAD are not known.Unilateral hindlimb ischemia was generated in mice as experimental PAD model, TMAO or 3,3 ...

การตรวจ trimethylamine n-oxide (TMAO) ในซีรัมเพื่อทำนายภาวะหลอดเลือดแข็งตัวในผู้ป่วยโรคไตเรื้อรัง

2023
ความเป็นมา: การเพิ่มขึ้นของสาร trimethylamine N-oxide (TMAO) ซึ่งเป็นสารพิษที่มาจากแบคทีเรียในลำไส้ของผู้ป่วยโรคไตเรื้อรัง (chronic kidney disease; CKD) อาจช่วยเพิ่มการผลิต TMAO reductase ซึ่งเป็นเอนไซม์ของแบคทีเรียในลำไส้และมีการแทรกผ่านไปยังกระแสเลือดอันเนื่องมาจากข้อบกพร่องในการซึมผ่านของลำไส้ (gut leakage) และอาจนำมาใช้เป็นตัวบ่งชี้ภาวะหลอดเลือดแข ...

Ultraviolet absorption spectra of trimethylamine N-oxide

Journal of Molecular Spectroscopy, 1966
Abstract Ultraviolet absorption spectra of trimethylamine N-oxide were recorded in several solvents, a band being found around 198 mμ with ϵ ≈ 2350 in acetonitrile solvent. However, in ethyl alcohol and in water this band undergoes a large blue shift and decreases in intensity.

Trimethylamine N-oxidation in Turkish women with bacterial vaginosis

Pharmacogenetics, 1996
Bacterial vaginosis (BV) is the most common cause of vaginal discharge in women of child-bearing age. A common symptom of this condition is a fishy-smelling vaginal discharge. Trimethylamine (TMA) is the substance which is primarily responsible for this distinctive odour.
