505 REAC 447: Qualitative Testing for Lipids Post-Laboratory Questions (Use the spaces provided for the answers and additional paper if necessary.) Lecithin A student used the procedure described in this experiment to try to determine the identity of an un- known. The lipid formed an emulsion when mixed with oil and water, reacted with aqueous sodium hydroxide to form soap, did not react with bromine, and gave a positive result for the ammonium molybdate test. De- scribe a lipid structure consistent with these results. 1. Explain what happened when you added lecithin to the mixture of oll and water. Identify the structural features of lecithin molecules responsible for this result. 3. Hbecame a cloudvorange Solution blcitlowers, Cholesterol. Itis not a positive result Cholestero! 2. Write a balanced chemical equation for the reac- tion of bromine and triolein, a triglyceride of oleic acid, CH3(CH2),CH=CH(CH2),COOH. 4.
