Seasonal variation of aliphatic amines in marine sub-micrometer particles at the Cape Verde islands [PDF]

open access: yes, 2009
Monomethylamine (MA), dimethylamine (DMA) and diethylamine (DEA) were detected at non-negligible concentrations in sub-micrometer particles at the Cap Verde Atmospheric Observatory (CVAO) located on the island of São Vicente in Cape Verde during algal ...

Oxidation of tertiary amine-derivatized surfaces to control protein adhesion [PDF]

open access: yes, 2013
Selective oxidation of omega-tertiary amine self-assembled thiol monolayers to tertiary amine N-oxides is shown to transform the adhesion of model proteins lysozyme and fibrinogen upon them.

A New ‘Off–On’ System Based on Core‐Substituted Naphthalene Diimide with Dimethylamine for Reversible Acid–Base Sensing

open access: yesChemistryOpen, 2022
A new ‘Off–On’ system designed and synthesised by functionalisation of a naphthalene diimide (NDI) core with dimethylamine produces 4,9‐bis(dimethylamino)‐2,7‐dioctylbenzo[lmn][3,8]‐phenanthroline‐1,3,6,8‐(2H,7H)‐tetraone, abbreviated as DDPT (1). DDPT 1

H2SO4 and particle production in a photolytic flow reactor: chemical modeling, cluster thermodynamics and contamination issues [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Size distributions of particles formed from sulfuric acid (H2SO4) and water vapor in a photolytic flow reactor (PhoFR) were measured with a nanoparticle mobility sizing system. Experiments with added ammonia and dimethylamine were also performed. H2SO4(g)

Endogenous formation of dimethylamine [PDF]

open access: yesBiochemical Journal, 1985
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 trimethylamine (TMA), which, in turn, is a breakdown product of dietary choline.

Substrate-Assisted Catalysis Unifies Two Families of Chitinolytic Enzymes [PDF]

open access: yes, 1997
Hen egg-white lysozyme has long been the paradigm for enzymatic glycosyl hydrolysis with retention of configuration, with a protonated carboxylic acid and a deprotonated carboxylate participating in general acid-base catalysis.

Analysis of Mono-, Di- and Oligosaccharides by CE Using a Two-Stage Derivatization Method and LIF Detection. [PDF]

open access: yes, 2009
A sensitive CE with LIF method has been developed for quantitative analysis of small carbohydrates. In this work, 17 carbohydrates including mono-, di- and oligosaccharides were simultaneously derivatized with 4-fluoro 7-nitrobenzo furazane (NBD-F) via ...
