Macromolecules/Biomolecules Summary

Here's a summary of macromolecules/biomolecules, including monomers, elements, functions, and examples for each category:

### Carbohydrates
- **Monomer (Building Block)**: Monosaccharides
- **Elements**: Carbon (C), Hydrogen (H), Oxygen (O)
- **Function**: Provide quick energy, serve as structural components, and play a role in cell signaling.
- **Example**: Glucose, Fructose, Sucrose, Starch, Cellulose.

### Lipids
- **Monomer (Building Block)**: Fatty acids and Glycerol
- **Elements**: Carbon (C), Hydrogen (H), Oxygen (O) (and Phosphorus (P) for phospholipids)
- **Function**: Store long-term energy, form cell membranes, and act as signaling molecules (hormones).
- **Example**: Triacylglycerols (fats and oils), Phospholipids, Cholesterol, Steroids.

### Proteins
- **Monomer (Building Block)**: Amino acids
- **Elements**: Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), and sometimes Sulfur (S)
- **Function**: Catalyze biochemical reactions (enzymes), provide structure, transport molecules, and regulate processes (hormones).
- **Example**: Hemoglobin (oxygen transport), Enzymes (like catalase), Antibodies (immune response), Collagen (structural).

### Nucleic Acids
- **Monomer (Building Block)**: Nucleotides
- **Elements**: Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), and Phosphorus (P)
- **Function**: Store and transmit genetic information; guide protein synthesis.
- **Example**: DNA (Deoxyribonucleic Acid), RNA (Ribonucleic Acid).

This summary encapsulates key aspects of the four main macromolecules essential for life.
