Dual-Pathway Glyoxal–Peptide Reaction Mechanisms under Acidic and Alkaline Conditions for Camellia oleifera Protein-based Adhesive Performance Optimization

BioResources
The pH-mediated regulation of the glyoxal-dipeptide reaction pathway was systematically investigated via electrospray ionization mass spectrometry (ESI-MS) and nuclear magnetic resonance (13C-NMR) spectroscopy.

Detection of ozone based on its striking inhibition of tris(1,10-phenanthroline)ruthenium(II)/glyoxal electrochemiluminescence

, 2014
Ozone unexpectedly dramatically suppresses the electrochemiluminescence (ECL) of Ru(phen)(3)(2+)/glyoxal at an ozone/glyoxal ratio of less than 0.5%. Moreover, a sensitive, simple and fast ECL method for ozone detection is developed, with a detection ...

Oligomer Formation in Evaporating Aqueous Glyoxal and Methyl Glyoxal Solutions

Environmental Science & Technology, 2006
Glyoxal and methyl glyoxal are common secondary atmospheric pollutants, formed from aromatic and terpene precursors. Both compounds are extremely water-soluble due to dihydrate formation and partition into cloudwater. In this work, FTIR-ATR and mass measurements indicate that both compounds remain primarily in the condensed phase due to oligomer ...

Photochemical Reactions of Glyoxal During Particulate Ammonium Nitrate Photolysis: Brown Carbon Formation, Enhanced Glyoxal Decay, and Organic Phase Formation

Environmental Science & Technology, 2022
Glyoxal is an important precursor of aqueous secondary organic aerosol (aqSOA). Its photooxidation to form organic acids and oligomers and reactions with reduced nitrogen compounds to form brown carbon (BrC) have been extensively investigated separately,

Synthesis of glyoxalic acid from glyoxal

Process Biochemistry, 2000
Abstract A chemo-enzymic route was devised for the synthesis of glyoxalic acid from glyoxal. Glyoxal was converted chemically to glycolic acid, which was oxidised to glyoxalic acid with a glycolate oxidase from spinach. The two steps were studied independently as well as singly. The conversion of glyoxal to glycolic acid was 95% at a mol ratio of 1:1.
