Here is still another lipid-related question. a. Draw the structure of a soap molecule, derived from a myristic acid triglyceride. No sticks. You CAN bunch the CH2 groups together. b. Write the COMPLETE AND BALANCED reaction for your soap reacting with hard water containing Fe*. NO STICKS! c. Describe what you would see if you used a detergent (rather than a soap) in the presence of Fe*. The more detail you give, the more points you will earn. No reactions are needed here.
