Urea and methylamines have similar effects on aldose reductase activity

open access: yes, 1997
The concentration of urea in renal medullary cells is sufficiently high to inhibit activity of many enzymes, yet the cells survive and function. The generally accepted explanation is the counteracting osmolytes hypothesis, which holds that methylamines ...

Modeling of ammonia and methylamine absorption with water on a new regular packing

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2019
Relevance of the work is caused by the lack of mathematical description of ammonia and methylamines absorption from multicomponent gas mixtures in a regular packing.

H‐Bonding‐Induced Repulsion Between Small Groups Toward a Highly Puckered Benzene

open access: yesAdvanced Science, EarlyView.
A benzene derivative bearing methylamino and nitro substituents adopts a boat‐shaped ring conformation. Comparison with four related compounds supports a role for intramolecular hydrogen bonding in constraining substituent orientations and promoting local steric crowding associated with ring puckering.

Effects of early tidal inundation on the cycling of methylamines in inter-tidal sediments.

open access: yes, 2005
This is one of two papers (also Marine Chemistry, 2006, 101, 12-26) reporting on the factors influencing the phase distribution of methylamines and ammonium in European estuaries.

A Quantitative Method to Measure and Speciate Amines in Ambient Aerosol Samples

open access: yesAtmosphere, 2020
Ambient reactive nitrogen is a mix of nitrogen-containing organic and inorganic compounds. These various compounds are found in both aerosol- and gas-phases with oxidized and reduced forms of nitrogen.

Ideas and perspectives: on the emission of amines from terrestrial vegetation in the context of new atmospheric particle formation [PDF]

open access: yesBiogeosciences, 2015
In this article we summarise recent science which shows how airborne amines, specifically methylamines (MAs), play a key role in new atmospheric particle formation (NPF) by stabilising small molecule clusters.

Oxidation of methylamine

open access: yesInternational Journal of Chemical Kinetics, 2020
AbstractA detailed chemical kinetic model for oxidation of methylamine has been developed, based on theoretical work and a critical evaluation of data from the literature. The rate coefficients for the reactions of CHNH + O CHNH / CHNH + HO, CHNH + H CH + NH, CHNH CHNH, and CHNH + O CHNH + HO were calculated from ab initio theory. The mechanism was

The Oxidation of Methylamine in Paracoccus denitrificans [PDF]

open access: yesEuropean Journal of Biochemistry, 1995
The in vivo oxidation of methylamine has been studied in Paracoccus denitrificans. Four components are involved in the electron transfer from methylamine to oxygen; methylamine dehydrogenase (MADH), amicyanin, cytochrome c and cytochrome‐c oxidase. In P. denitrificans, MADH and its electron acceptor amicyanin are indispensable for growth on methylamine.
