Measurement of methylamines in seawater using solid phase microextraction and gas chromatography

open access: yesLimnology and Oceanography: Methods, 2018
The methylamines form part of the marine organic nitrogen pool. Although they are ubiquitous in marine systems, little is known about their distribution, production, and fate in the marine environment.

Testing the ability of non-methylamine osmolytes present in kidney cells to counteract the deleterious effects of urea on structure, stability and function of proteins. [PDF]

open access: yesPLoS ONE, 2013
Human kidney cells are under constant urea stress due to its urine concentrating mechanism. It is believed that the deleterious effect of urea is counteracted by methylamine osmolytes (glycine betaine and glycerophosphocholine) present in kidney cells. A

The salting coefficient and size of alkylamines in saline media at different temperatures: estimation from Pitzer equations and the mean spherical approximation [PDF]

open access: yes, 2001
The renewed theoretical interest in the proton transfer associated to the amino group together with the scarcity of acid-base studies of amines in moderate to concentrated saline media focussed our attention on the study of the basicities of some ...

Reduction of trimethylamine N-oxide to trimethylamine by the human gut microbiota: supporting evidence for ‘metabolic retroversion’ [PDF]

open access: yes, 2015
Dietary sources of methylamines such as choline, trimethylamine (TMA), trimethylamine N-oxide (TMAO), phosphatidylcholine (PC) and carnitine are present in a number of foodstuffs, including meat, fish, nuts and eggs.

Uncovering the Diversity and Activity of Methylotrophic Methanogens in Freshwater Wetland Soils

open access: yesmSystems, 2019
Wetland soils are one of the largest natural contributors to the emission of methane, a potent greenhouse gas. Currently, microbial contributions to methane emissions from these systems emphasize the roles of acetoclastic and hydrogenotrophic methanogens,

Development and Application of a UPLC–MRM–MS Method for Quantifying Trimethylamine, Trimethylamine-N-Oxide, and Related Metabolites in Individuals with and Without Metabolic Syndrome

open access: yesSeparations
Trimethylamine-N-oxide (TMAO) is associated with various chronic diseases. TMAO is a downstream oxidative metabolite of trimethylamine (TMA) that is generated by the gut microbiota from dietary choline, carnitine, and betaine.

Methylamines as Nitrogen Precursors in Chemical Vapor Deposition of Gallium Nitride

open access: yesJournal of Physical Chemistry C, 2018
Chemical vapor deposition (CVD) is one of the most important techniques for depositing thin films of the group 13 nitrides (13-Ns), AlN, GaN, InN and their alloys, for electronic device applications.

Synthesis and Characterization of New Copper(II) Coordination Compounds with Methylammonium Cations

open access: yesInorganics
We synthesized four new copper(II) complexes with acetato and chlorido ligands and methylammonium (MA), dimethylammonium (DMA), and tetramethylammonium (TMA) counterions: (MA)4[Cu2Ac4Cl2]Cl2·2H2O (1), (DMA)2[Cu2Ac4Cl2] (2), (DMA)4[Cu2Ac4Cl2]Cl2·2H2O (3),

Phylogenomic Reconstruction and Metabolic Potential of the Genus Aminobacter

open access: yesMicroorganisms, 2021
Bacteria belonging to the genus Aminobacter are metabolically versatile organisms thriving in both natural and anthropized terrestrial environments. To date, the taxonomy of this genus is poorly defined due to the unavailability of the genomic sequence ...
