Paraoxonase 1 (PON1) also known as Serum paraoxonase and arylesterase 1, A esterase, homocysteine thiolactonase or serum aryldialkylphosphatase 1, is an enzyme that in humans is encoded by the PON1gene.[5] Paraoxonase 1 has esterase and more specifically paraoxonase activity.[6]PON1 is the first discovered member of a multigene family also containing PON2 and PON3, the genes for which are located adjacent to each other on chromosome 7. PON1 on HDL (different from soluble PON1) is responsible for significant atheroprotection rendered by the HDL.[7]
