Concept explainers
(a)
Interpretation:
General structure for fatty acids, soaps, waxes, and triacylglycerols has to be drawn.
Concept Introduction:
Fatty acid leads to formation of lipid and consists of a carboxyl group
Soap is the long hydrocarbon chain with the metal salt of the fatty acid and is formed by the basic hydrolysis of triacylglycerol.
Waxes are type of nonpolar lipids that contain esters and are formed by the reaction of
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 triacylglycerols.
(b)
Interpretation:
Structure of example of fatty acids, soaps, waxes, and triacylglycerols has to be drawn.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Whether fatty acids, soaps, waxes, and triacylglycerols are water-soluble or not has to be identified.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
Whether fatty acids, soaps, waxes, and triacylglycerols are soluble in hexane or not has to be identified.
Concept Introduction:
Refer to part (a).
