1. Carbohydrates: These are the most common type, providing energy and structural support. They include:
* Sugars: Simple sugars like glucose and fructose, and disaccharides like sucrose and lactose.
* Starches: Complex carbohydrates like amylose and amylopectin, found in potatoes and grains.
* Cellulose: A complex carbohydrate that forms the cell walls of plants, providing structure.
2. Lipids (Fats and Oils):
* Fats: Solid at room temperature, mainly from animal sources. Examples include butter, lard, and cholesterol.
* Oils: Liquid at room temperature, mainly from plant sources. Examples include olive oil, sunflower oil, and vegetable oil.
3. Alcohols:
* Methanol (CH3OH): The simplest alcohol, used as a solvent and fuel.
* Ethanol (C2H5OH): Found in alcoholic beverages, also used as fuel and solvent.
* Glycerol (C3H8O3): A thick, syrupy liquid found in fats and oils, used as a moisturizer and in food products.
4. Carboxylic Acids:
* Acetic acid (CH3COOH): The main component of vinegar.
* Formic acid (HCOOH): Found in ant stings and bee venom.
* Citric acid (C6H8O7): Found in citrus fruits, used as a flavoring agent and preservative.
5. Other Organic Compounds:
* Formaldehyde (CH2O): A pungent gas used in preserving biological specimens and manufacturing plastics.
* Acetone (C3H6O): A solvent used in nail polish remover and other household products.
Key Points:
* The ratio of carbon, hydrogen, and oxygen atoms determines the specific molecule and its properties.
* These molecules play crucial roles in living organisms and are essential for various industrial processes.
* The study of these molecules is a vast field known as organic chemistry.
