We hear so much about how dangerous oxidized fats are, but I don't exactly understand what the chemical structure of an oxidized fat is. I know that saturated fats cannot be oxidized and polyunsaturated fats are most easily oxidized. Does an oxygen atom attach to the fat molecule in place of a hydrogen or a carbon double bond? Also, what happens in the body when an oxidized fat is ingested? How is it digested and what problems does it cause?
Please help me understand! Thank you!
