Biological Functions of Biomolecules

Carbohydrates: Primary source of immediate metabolic energy (e.g., Glucose) and structural support (e.g., Cellulose in plant cell walls).

Proteins: Catalytic enzymes, structural components (Keratin, Collagen), transport agents (Hemoglobin), and immune defense (Antibodies).

Nucleic Acids: Storage and transmission of hereditary genetic information (DNA) and synthesis of cellular proteins (RNA).

Lipids/Fats: Long-term energy storage, cell membrane structural integrity (Phospholipids), and thermal insulation.
