what are macromolecules give examples
Macromolecules are very large and complex molecules formed by the joining of many small units called monomers. They usually have high molecular mass and are essential for living organisms.
Types of macromolecules with examples
| Macromolecule | Examples | Function |
|---|---|---|
| Carbohydrates | Starch, Cellulose | Provide energy |
| Proteins | Hemoglobin, Enzymes | Growth and repair |
| Nucleic acids | DNA, RNA | Store genetic information |
| Lipids | Fats, Oils | Energy storage |
Characteristics of macromolecules
Large molecular size
Made of repeating smaller units
Important for body structure and functions
Importance
Macromolecules are necessary for:
Growth and development
Energy storage
Cell structure
Genetic inheritance
For example, DNA is a macromolecule that carries hereditary information from parents to offspring.
