1. Carbohydrates:
* Functions:
* Primary source of energy for cells
* Structural components of cell walls and exoskeletons
* Involved in cell signaling and recognition
* Examples:
* Glucose (simple sugar)
* Starch (complex carbohydrate)
* Cellulose (structural polysaccharide)
2. Lipids (Fats and Oils):
* Functions:
* Long-term energy storage
* Structural components of cell membranes
* Insulation and protection
* Hormones and signaling molecules
* Examples:
* Triglycerides (fats and oils)
* Phospholipids (cell membrane components)
* Steroids (hormones like cholesterol)
3. Proteins:
* Functions:
* Enzymes (catalyze biochemical reactions)
* Structural components (muscle, hair, skin)
* Transport and storage (hemoglobin, albumin)
* Antibodies (immune system)
* Hormones (insulin, growth hormone)
* Examples:
* Collagen (connective tissue)
* Insulin (regulates blood sugar)
* Antibodies (fight infections)
4. Nucleic Acids:
* Functions:
* Store and transmit genetic information
* Involved in protein synthesis
* Examples:
* DNA (deoxyribonucleic acid)
* RNA (ribonucleic acid)
These four classes of biomolecules are essential for all known forms of life and are involved in a wide range of biological processes, including:
* Metabolism: Breakdown and synthesis of molecules for energy and growth
* Growth and development: Building and maintaining tissues and organs
* Reproduction: Creating new organisms
* Response to stimuli: Adapting to changes in the environment
* Homeostasis: Maintaining internal balance
Without these organic compounds, life as we know it would not exist.
