1,2 They catalyze the conjugation of glutathione to many organic compounds, so that it can be more easily eliminated from the organism

These enable reproducible detection across a wide biochemical range (amino acids, bile acids, fatty acids, biogenic amines, indole derivatives), facilitating both discovery and translational research
