Linoleic acid is an unsaturated vegetable oil found in soybean, sunflower, and corn oils. Often these unsaturated vegetable oils are considered to be good for one's heart since unsaturated vegetable oils do not contribute to levels of bad cholesterol. However, it has been reported that heating linoleic acid at frying temperatures, such as 365°F for 30 minutes or longer, leads to the formation of a toxic aldehyde, (2E)-4-hydroxy-2-nonenal. What is the structure of (2E)-4-hydroxy-2-nonenal? If (2E)-4-hydroxy-2-nonenal was oxidized by PCC, what would be the expected product? If (2E)-4-hydroxy-2-nonenal was oxidized by Jones' reagent, what would be the expected product?
