Biomolecules are the essential chemical compounds that keep your body running. They include carbohydrates, proteins, lipids, and nucleic acids. Carbs give energy, proteins and amino acids build and repair tissues, lipids like triglycerides store energy and make hormones, and nucleic acids like DNA carry genetic information.

Key Points

• Support growth, energy, immunity, and hormone balance.
• Examples: Glucose (carb), hemoglobin (protein), triglycerides (lipids), DNA (nucleic acids).
• Essential for everyday body functions.
