THIS IS THE BEGINNING OF THE SHORT ANSWER SECTION OF THE EXAM. The questions below pertain to the following triglyceride: For 5 pts Clearly label on the picture above or on the lines below the following: ( 1 pt.) Show on the diagram a likely location for abstraction of a hydrogen during lipid free radical formation (3 pt.) Draw the resonance structures resulting from the loss of the hydrogen you identified. (1 pt.) Show two hydroperoxides that form as a result of the reaction you have shown. (Note: If you don't want to redraw the entire molecule, you may show portions of a fatty acid chain only, as long as the chain and the carbons are clearly and correctly identified. ) A hydrogen can be abstracted from the monounsaturated sn-2 fatty acid chain, from a carbon than is immediately next to the C=C double bond. For this particular chain, that means that the hydrogen is lost from either C8 or C11. The resulting free radical is stabilized in a resonance structure, as shown on the last page below. The two associated hydroperoxides are also shown in the diagram. O
