Begin by understanding the definition of biological molecules. Biological molecules are any molecules that are present in living organisms, including macromolecules like proteins, nucleic acids, carbohydrates, and lipids.
Identify the classes of biological molecules. The main classes include carbohydrates, lipids, proteins, and nucleic acids. These are essential for various biological functions and structures.
Carbohydrates are organic compounds consisting of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They serve as energy sources and structural components in cells.
Lipids are a diverse group of hydrophobic molecules, including fats, oils, and steroids. They are important for energy storage, cell membrane structure, and signaling.
Nucleic acids, such as DNA and RNA, are polymers made of nucleotide monomers. They store and transmit genetic information in cells.
