Paraoxonase 1 (PON1) is a serum high-density lipoprotein-bound enzyme with antioxidant function. It hydrolyses lipid peroxides, protecting low-density lipoproteins from oxidative modifications. Patients with psoriasis are at greater risk of oxidative stress, which is associated with abnormal plasma lipid metabolism.
