Question
Chapter 20.2, Problem 3P
Interpretation Introduction
Interpretation:
Structure for an optically inactive fat that, when hydrolysed under acidic condition gives glycerol with one equivalent lauric acid and two equivalents of stearic acid has to be identified.
Concept Introduction:
Triglycerides are compounds in which the three
Triglycerides that are solids or semisolids at room temperature are fats and liquid triglycerides are oils.

4. The ester you drew in Question #1 has a melting point range of 32-35 °C. The methyl ester of mono-unsaturated
palmitoleic acid (IUPAC name: hexadec-9enoic acid) has a considerably lower melting point range: -0.5-+0.5 °C.
a) Explain what it means for a fatty acid to the "mono-unsaturated."
b) Illustrate your explanation by drawing the structure of the methyl ester of octadec-11-enoic acid. (Be sure to draw
the geometric stereoisomer that is commonly found in nature.)
6. Why do carbohydrates burn less calories
per gram than fatty acids?
1. Draw, using condensed structural formulas, all reactants and products of the saponification reaction of a triacylglycerol using NaOH. Use lauric acid, a 12-carbon saturated fatty acid found in vegetable shortening.
2. Soap can be made using a variety of different fats, oils and bases. Suppose a student wanted to make a soft, liquid soap that lathers easily. What type(s) of fat/oil and base would you recommend? How would this differ from making a solid bar of soap?
3. Vegetable oils are typically liquid at room temperature, yet Crisco (which is made of vegetable oil) is solid at room temperature. Explain why/how this is the case.
4. Explain, with the use of a diagram how soap molecules work to clean “dirt” particles.
5. Amylase is a natural enzyme found in saliva. Describe this enzyme’s function.
6. Lactose is a sugar found in milk and other dairy products. Explain how it is broken down in most individuals. Explain lactose “intolerance”.
