The question asked for how many products are formed by complete hydrolysis of phosphatidylethanolamine. I can see how three products can be formed, but where did the other two (palmitic acid and oleic acid) come from?

Thanks!

every ester group is hydrolyzed, so break the molecule where ever u see an ester oxygen . This hydrolysis occurs twice on the phosphate bc it has two ester links(diester bond)
