Nomen ___________ Lipids Identification Worksheet Part A. Identify each molecule as a triglyceride, phospholipid, or steroid. How do you know? Molecule What is it? How can you identify it? Part B. Identify the fatty acid as saturated or unsaturated. Then, re-draw it as a line structure. Fatty acid Saturated Line structure or unsaturated? You will practice showing the formation of a triglyceride by condensation. (a) In your notebook, draw the molecular structures below. (b) Circle the atoms that will be removed during a condensation reaction. Glycerol Saturated fatty acid with 7 carbon atoms Monounsaturated trans fatty acid with 9 carbon atoms (show the double bond between carbons 4 and 5)
