Important organic molecules are characterized by the presence of carbon and are fundamental to life. These molecules range from simple to highly complex, serving diverse roles in biological systems. Here are some notable examples:
Small Organic Molecules
- Methane (CH4): A simple hydrocarbon molecule, it is a primary component of natural gas.
Macromolecules
Macromolecules are large, complex organic molecules built from smaller repeating units. They play crucial roles in living organisms.
-
Carbohydrates:
- Glucose: A simple sugar (monosaccharide) that serves as a primary energy source for cells.
-
Lipids:
- Triglycerides: Fats and oils used for energy storage and insulation.
-
Nucleic Acids:
- DNA (Deoxyribonucleic Acid): The molecule that carries genetic information.
-
Proteins:
- Lactase: An enzyme that helps break down lactose, a sugar found in milk. Enzymes, in general, facilitate biochemical reactions in cells.
