Vedclass · Answer

(A) Oils are liquids at room temperature because they contain a high proportion of unsaturated fatty acid residues,such as oleic acid,linoleic acid,and linolenic acid. These residues form esters known as oleates. In contrast,fats are solids at room temperature and contain a high proportion of saturated fatty acid residues like myristic,palmitic,and stearic acids. For example,glyceryl trioleate (triolein) is an oil,while glyceryl tristearate (tristearin) is a fat.
