Chapter 3, Problem 2AC
Summary Introduction
To explain:
Comparison of the way the fat and carbohydrate molecules interact with water and explain the way this interaction gives fat an extra advantage for weight efficient energy storage.
Concept Introduction:
Fats are the lipid molecules inside the cell. These fat molecules are of two types called saturated and unsaturated molecules. The saturated molecules consist of a carbon atom with a single bond in between them whereas the unsaturated molecules have a double bond between the carbon atoms. Carbohydrates are
