Detailed explanation-3: -Refined corn oil is composed of 99% triacylglycerols with polyunsaturated fatty acid (PUFA) 59%, monounsaturated fatty acid 24%, and saturated fatty acid (SFA) 13%. The PUFA is linoleic acid (C18:2n-6) primarily, with a small amount of linolenic acid (C18:3n-3) giving a n-6/n-3 ratio of 83.

Detailed explanation-4: -Fats and oils belong to a group of biological substances called lipids. Lipids are biological chemicals that do not dissolve in water.
