Question
Chapter 31, Problem 31.21P
Interpretation Introduction
Interpretation: The possible constitutional isomers of as triacylglycerol formed from one mole of each palmitic acid, oleic and linoleic acid are to be drawn and the stereogenic centers are to be located in each constitutional isomer.
Concept introduction: Triacylglycerols are a type of lipids. They are composed of three fatty acids and glycerol. Simple triacylglycerol contains three same fatty acids while mixed triacylglycerol contains two or more different fatty acids. They are also known as triglycerides.
