Acylglycerol consists of a glycerol molecule linked to three fatty acids. Saturated acylglycerols contain saturated fatty acids i. they do not contain any double bond between carbon atoms. Hence, this option is incorrect.
Acylglycerol consists of a glycerol molecule linked to three fatty acids. Unsaturated acylglycerols contain one or more than one double bond between carbon atom (-C=C-). Hence, this option is incorrect.
A phospholipid is similar to Triacylglycerol of an oil, except that one fatty acid is replaced by a phosphate group. Hence, this option is incorrect.
Waxes are simple lipids having one molecule of fatty acid forming ester bond with one molecule of long chain alcohol e.g Bee's wax. Hence, this option is correct.
