1. Carbohydrates: These are made up of carbon, hydrogen, and oxygen. They serve as energy sources and structural components in cells. Examples include sugars, starches, and cellulose.

2. Lipids (Fats): These are also made up of carbon, hydrogen, and oxygen, but with a higher proportion of hydrogen. They provide long-term energy storage, insulation, and protection for organs. Examples include fats, oils, and waxes.

3. Proteins: These are made up of carbon, hydrogen, oxygen, and nitrogen. They are the workhorses of the cell, performing a wide variety of functions, including structural support, catalysis, transport, and defense. They are made up of amino acid monomers.

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