(a)
Interpretation:
Basic hydrolysis of triacylglycerol to form soap of below structure has to be determined.
Concept Introduction:
Triacylglycerols are lipids that are formed by two or more similar or different fatty acids. They are also called triglycerides and are hydrophobic and nonpolar in nature. Addition of glycerol and three similar or different fatty acids results into triesters that is also triacylglycerols.
Soap is the long hydrocarbon chain with the metal salt of the fatty acid and is formed by the basic hydrolysis of triacylglycerol. For example, sodium stearate is the sodium salt of stearic acid as shown below.
Basic hydrolysis of triacylglycerol with water in presence of base produces metal salt of fatty acid and alcohol. The reaction that explains the basic hydrolysis of triacylglycerol is as follows:
Here,

- Draw the general block diagram for a triacylglycerol.arrow_forwardDraw structures of glyceryl tripalmitate and glyceryl trioleate. Which would you expect to have a higher melting point?arrow_forwardThe plasmalogens are a group of lipids found in nerve and muscle cells. How do plasmalogens differ from fats?arrow_forward
- Describe the structure of a micelle formed by the association of fatty acid molecules in water. What forces hold the micelle together?arrow_forwardWhy metals are deleterious to the stability of unsaturated fatty acids? I. They initiate free radicals which lead to autoxidation of the fatty acids II. They bind to the double bonds and create an undesirable metallic taste III. They cause the formation of dimers of two or more fatty acids which changes the melting point IV. They will solidify the unsaturated fatty acid а. I and III b. I, II, III and IV c. I only d.

Ascorbic acidarrow_forwardIf a person produces and exudes a polyunsaturated oil from their skin, how does it ultimatum make closeness smell bad and how does baking soda remove the odorarrow_forward
- What is the composition of the soap prepared by hydrolysis of the following triacylglycerol?arrow_forward1.The reaction that is required in making soap is: ester hydrolysis hydration esterification hydrogenation 2. Micelles stay in the soap solution as colloid since: negative charges from polar heads repel each other positive charges from polar heads are attraced to each other positive charges from polar heads repel each other negative charges from polar heads are attracted to each other 3.The soap that would take longer to lather has: shorter chained fatty-acid salts saturated carbon atoms longer chained fatty-acid salts more potassium ionsarrow_forwardFatty acids are distributed throughout the body, via a time-release/transport molecule created by: a. an esterification reaction with glycerol b. a hydrolytic reaction with methylamine c. an alkylation reaction with butanol d. a carboxylation reaction with lactic acid e. an ether formation reaction with ethylene glycolarrow_forward
