Extended Data Fig. 6: Chemical structures of glyoxal compounds used in this study.
From: Global profiling of arginine reactivity and ligandability in the human proteome

Glyoxal compounds are categorized into three structural types: aryl-disubstituted glyoxals (Type 1), alkyl-disubstituted glyoxals (Type 2), and monosubstituted glyoxals (Type 3).
