Biomolecules are organic molecules produced by living organisms. They include carbohydrates, proteins, lipids, and nucleic acids.
These are energy-rich organic compounds made up of carbon, hydrogen, and oxygen atoms. They serve as fuel for our bodies.
Complex molecules made up from chains of amino acids that perform numerous functions within organisms such as catalyzing metabolic reactions or replicating DNA.
These are large biomolecules essential for all known forms of life. They carry genetic information - DNA and RNA are examples.
