How do lipids differ from carbohydrates and proteins?
Lipids have varied structures, but all have a polar "head" and a large nonpolar "tail"".
Fats and oils are typical lipids.
The structure of a typical fat is
The molecule is mostly nonpolar hydrocarbon with some polar
Proteins are large molecules that consist of long chains of amino acids joined together by peptide (
The structure of a small protein is
Proteins have polar
Carbohydrates have many polar
A typical carbohydrate is starch, which is consists of many glucose units (
Most carbohydrates are hydrophilic and soluble in water because of their polar
