Concept explainers
(a)
Interpretation:
A triacylglycerol formed from lauric, myristic and linoleic acids should be drawn.
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:
An unsaturated triacylglycerol that contains two cis double bonds in one fatty acid side chain should be drawn.
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.
(c)
Interpretation:
A saturated triacylglycerol that formed from three 14-carbon fatty acids should be drawn.
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.
(d)
Interpretation:
A monounsaturated triacylglycerol should be drawn.
