Which option correctly lists all four main categories of biochemicals?

• A. Carbohydrates, Lipids, Proteins, Nucleic Acids
• B. Carbohydrates, Lipids, Nucleic Acids, Minerals
• C. Carbohydrates, Proteins, Lipids, Nucleic Acids
• D. Lipids, Proteins, Carbohydrates, Nucleic Acids

Answer: (A)

Biochemicals are organized into four major classes: carbohydrates, lipids, proteins, and nucleic acids. This grouping reflects the main types of organic molecules that build cells and drive biology. Each class is defined by its monomer units and typical functions: carbohydrates from sugars, providing quick energy and structural roles; lipids from fatty acids and glycerol, forming cell membranes and long‑term energy storage; proteins from amino acids, carrying out structure, enzymes, signaling, and transport; nucleic acids from nucleotides, encoding genetic information and guiding protein synthesis. Minerals are essential but are inorganic substances and not part of these four organic biomolecule categories. The four categories can be listed in any order, but their identities remain the same. Therefore, the correct set is carbohydrates, lipids, proteins, nucleic acids.
