    • Constipation
    • Coronary Heart Disease
    • Starvation
    • Obesity (leads to type II diabetes and hypertension)
    • Scurvy
  • Biomolecules
    Carbohydrates, proteins, and fats are also known as biomolecules. These are molecules produced by cells and living organisms. They also make up living organisms.
  • Carbohydrates
    Made of long chains of identical small sugar molecules. The long chains are broken down into smaller sugar molecules by the body, which are used to release energy and make the body work.
  • Proteins
    Made of long chains of small molecules called amino acids. There are 20 different kinds of amino acid. Proteins are used by the body for growth and repair.
  • Fats
    Made up of fat molecules which contain fatty acids and glycerol. Fat molecules have to be broken down by the body so that they can be used for energy storage. Fats are also used by the body to keep heat in and to make cell membranes.
