Question
Chapter 26, Problem 2P
Interpretation Introduction
Interpretation:
The correct option involved in the formation of sphingolipids should be determined.
Concept introduction:
Phospholipidsare the basic constituent of all cell membranes. They usually form lipid bilayers. The structure of a phospholipid molecule has a tail made up of two hydrophobic fatty acid and a hydrophilic head comprising of a phosphate group.
