A) How is the shape of saturated fatty acids different from the shape of unsaturated fatty acids? What causes this difference?

Explanation:

Saturated fatty acids have only single bonds between them. This means that, without hydrogens between them, they are solid at room temperature and they have a higher melting point, requiring more energy to break the bond. Unsaturated fatty acids, however, have a double bond between one or more of the carbon atoms.
