Secondary Organic Aerosol-Forming Reactions of Glyoxal with Amino Acids

, 2009
Glyoxal, the simplest and most abundant α-dicarbonyl compound in the atmosphere, is scavenged by clouds and aerosol, where it reacts with nucleophiles to form low-volatility products.

Heterogeneous Glyoxal Oxidation: A Potential Source of Secondary Organic Aerosol

, 2016
Laboratory studies are described that suggest reactive uptake of glyoxal on particulate containing HNO3 could contribute to the formation of secondary organic aerosol (SOA) in the upper troposphere (UT).

Dicarbonyl compounds and sugar contents of Thai commercial beverages [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2013
Glyoxal (GO) and methylglyoxal (MGO), two -dicarbonyl compounds (RCS) found in humans, cause carbonyl stress following the formation of advanced glycation end products (AGEs). Both are linked to many chronic diseases.

Laser-Excited Emission from Glyoxal and Its Deuterated Derivatives

, 1973
Emission spectra of glyoxal, glyoxal-d1, and glyoxal-d2 have been excited using the various lines of an argon ion laser. The bands have been assigned to 3 band systems, viz. the 1Au–1Ag and 3Au–1Ag (π*–n) systems of the trans molecule and the 1B1–1A1 (π*
