1. Carbohydrates: These are made up of carbon, hydrogen, and oxygen. They provide energy for the body and are important structural components of cells. Examples include sugars, starches, and cellulose.

2. Lipids (Fats and Oils): Also made up of carbon, hydrogen, and oxygen, but with a higher proportion of hydrogen. Lipids store energy, provide insulation, and form cell membranes. Examples include butter, oils, and cholesterol.

3. Proteins: Composed of carbon, hydrogen, oxygen, and nitrogen, sometimes also containing sulfur. Proteins are essential for building and repairing tissues, transporting substances, and regulating chemical reactions. Examples include enzymes, antibodies, and muscle fibers.

4. Nucleic Acids: These are made up of carbon, hydrogen, oxygen, nitrogen, and phosphorus. Nucleic acids carry genetic information and are responsible for protein synthesis. Examples include DNA and RNA.
