Part 1: Triacylglycerols (Triglycerides) 1. Build a triglyceride made with palmitoleic, oleic and myristic acids (you do not have to connect the hydrogens of the fatty acids). Draw the line structure of the molecule. Circle the hydrophobic region of the molecule. Put a box around the hydrophilic region of the molecule. 2. Predict the physical state this substance would be in at room temperature. Explain your reasoning. 3. Write an equation (line structures) for a hydrogenation reaction of the triglyceride. Construct the necessary hydrogen molecules and carry out the reaction with the model. Pd 57 Q 2 4. Write an equation (line structures) for the hydrolysis of the triglyceride in the presence of NaOH.
