Identify the four major types of biomolecules: carbohydrates, lipids, proteins, and nucleic acids.
Understand that biomolecules are organic compounds, which means they are primarily composed of carbon atoms bonded with other elements.
Recognize that hydrogen and oxygen are also fundamental components of all biomolecules, as they are involved in forming water and various functional groups.
Consider the role of nitrogen, phosphorus, and sulfur: while they are important in certain biomolecules (e.g., nitrogen in proteins and nucleic acids, phosphorus in nucleic acids, sulfur in some amino acids), they are not present in all four types.
Conclude that the elements common to all four major types of biomolecules are carbon, hydrogen, and oxygen, as these are the basic building blocks of organic molecules.
