Chapter 26, Problem 30PP

Interpretation Introduction

Interpretation:

Two possible structures of cephalin need to be drawn and to discuss whether the compounds are chiral.

Concept introduction:

Phosphoglycerides are same as triglycerides but the only difference is that in triglycerides there are three fatty acid residues.  But in phosphoglyceride one of the fatty acid residues in triglyceride is replaced by a phosphoester.  Hydrolysis of phosphoglycerides yield glycerol, fatty acid, phosphate.

To draw: the two possible structure of cephalins and check whether both are chiral.
