Introduction

Phase 2 enzymes (in general) reduce toxicity of the products of phase 1 enzymes. They include enzymes catalyzing conjugation of xenobiotics to endogenous ligands, glucuronate & glutathione to confer aqueous solubility to hydrophobic molecules for clearance from the body.

Phase 2 enzymes may be encoded by genes that contain the antioxidant response element (ARE).

Phase 2 enzymes include:
