Lipase is an enzyme that catalyzes the breakdown of lipids by hydrolyzing triglycerides. This is important for digestion and promoting absorption of fats in the intestines. Part 1. Triglycerides Triglycerides are composed of three fatty acids connected to a glycerol backbone. The functional group that connects the fatty acids to the glycerol is circled. ⋅ (1 pt ) Identify this functional group: _____________ ⋅ (1 pt) This functional group is an electrophile. How reactive is this functional group? Circle one. Very reactive Reacts with acid/base catalysis Unreactive ⋅ (5 pts) Draw the curved arrows for each step of the hydrolysis of a triglyceride in aqueous solution. O O
