Abstract: Abstract Gaseous glyoxal and methylglyoxal concentrations were characterized in nine cities of China during 2010–2011. The average summer (winter) glyoxal and methylglyoxal concentrations were 36.4–178.4 (12.3–241.4) and 67.8–359.4 (28.4–530.0) ng/m 3 , respectively. In summer,… read more here.

DOI: 10.1016/j.ijbiomac.2017.08.180
Abstract: Glyoxal, a reactive α-oxoaldehyde, increases in diabetic condition. It reacts with different proteins to form advanced glycation end products (AGEs) following Maillard-like reaction. Considering the significance of AGE-mediated protein modification by glyoxal, here we have… read more here.

DOI: 10.1021/acs.jafc.2c00906
Abstract: Short-chained α-hydroxycarbonyl compounds such as glycolaldehyde (GA) and its oxidized counterpart glyoxal (GX) are known as potent glycating agents. Here, a novel fluorescent lysine-lysine cross-link 1-(5-amino-5-carboxypentyl)-3-(5-amino-5-carboxy-pentylamino)pyridinium salt (meta-DLP) was synthesized and its structure unequivocally proven… read more here.
