Trimethylamine N-Oxide (TMAO) as a Biomarker
2022The 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

A new two-step synthetic pathway developed for the transformation of arsenic trioxide [iAs(III); As(2)O(3)] into arsenobetaine (AB; Me(3)As(+)CH(2)CO(2)(-)) involves treatment of iAs(III) with native B(12) or biomimetic B(12) in the presence of glutathione (GSH) to give TMAO with a high selectivity and a high conversion rate; subsequent treatment of ...

Journal of Molecular Liquids, 2017
Abstract We have performed the molecular dynamics simulations study to investigate the interaction of different force-field parameters of trimethylamine-N-oxide (TMAO) with aqueous solution of N-methylacetamide (NMA). We have calculated the number and energies of NMA-water, water-water and TMAO-water hydrogen bonds along with their hydrogen-bond ...

Temperature induced change of TMAO effects on hydrophobic hydration
The Journal of Chemical Physics, 2022The effect of trimethylamine-N-oxide (TMAO) on hydrophobic solvation and hydrophobic interactions of methane has been studied with Molecular Dynamics simulations in the temperature range between 280 and 370 K at 1 bar ambient pressure. We observe a temperature transition in the effect of TMAO on the aqueous solubility of methane.

TMAO and urea in the hydration shell of the protein SNase
Physical Chemistry Chemical Physics, 2017We performed all-atom MD simulations of the protein SNase in aqueous solution and in the presence of two major osmolytes, trimethylamine- N -oxide (TMAO) and urea, as cosolvents at various concentrations and compositions and at different pressures and temperatures.

Five molecular models for trimethylamine N-oxide (TMAO) to be used in conjunction with compatible models for liquid water are evaluated by comparison of molecular dynamics (MD) simulation results to experimental data as functions of TMAO molality. The experimental data comprise thermodynamic properties (density, apparent molar volume, and partial molar

Localization, characterization and partial purification of TMAO-ase
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19821. Formaldehyde (FA) and dimethylamine (DMA) are generated in several species of fish of commercial importance. 2. The present study describes the localization, partial purification and characterization of an enzyme recovered from cod kidney tissue which is responsible for the reduction of trimethylamine oxide (TMAO) to FA and DMA. 3.

Classical molecular dynamics simulation of GB1 peptide (a 16-residue β-hairpin) in different osmotic environments is studied. Urea is used for denaturation of the peptide, and trimethylamine-N-oxide (TMAO) is used to offset the effect of urea. Protein-urea electrostatic interactions are found to play a major role in protein-denaturation.
