(a)
Interpretation:
The fatty acids that are used to form the given triacylglycerol should be determined.
Concept Introduction:
Triacylglycerols are esters that are formed by reacting three molecules of fatty acids with one molecule of glycerol. If all the three fatty acids are identical it is called a simple triacylglycerol and if there are two or more different fatty acids, it is called a mixed triacylglycerol. Depending on whether the fatty acids involved are saturated or unsaturated, there are two types of triacylglycerols.
(b)
Interpretation:
Whether the triacylglycerol is expected to be a solid or a liquid at room temperature should be determined.
