Objective: Oxidative stress may change cellular function in multiple pathological conditions, including osteoporosis. We aimed to determine malondialdehyde (MDA) levels, advanced oxidation protein pruducts (AOPP), levels end products of protein oxidation, thiol as known antioxidant, serum paraoxonase 1 (PON1) activities as known lipid antioxidant, induced by reactive oxygen species (ROS) for evaluating oxidative stress in osteoporotic patients. Methods: 59 patients diagnosed with postmenopaual osteoporosis were included in the study and compared with 21 healthy controls. Serum AOPP, MDA, thiol levels and PON1 activity were measured according to an enzymatic spectrophotometric method. Results: The serum MDA, AOPP, and thiol levels was significantly higher in the patient group than controls (p
