Question
Chapter 19.7, Problem 6QQ
Interpretation Introduction
Interpretation: The two tails in the structural model for phospholipids have to be identified.
Concept introduction: The most abundant type of membrane lipid is phospholipids. A lipid which contains a platform molecule, to which one or more fatty acids and a phosphate group are attached, is known as phospholipid.
