Carbohydrates:
* Glucose: A simple sugar used as the primary energy source by many organisms.
* Starch: A complex carbohydrate made up of many glucose molecules linked together, found in plants as a storage form of energy.
* Cellulose: Another complex carbohydrate, also made of glucose, that forms the rigid cell walls of plants.
Lipids (Fats and Oils):
* Triglycerides: The main form of fat storage in animals and plants, made up of glycerol and three fatty acids.
* Phospholipids: A key component of cell membranes, they have a hydrophilic (water-loving) head and hydrophobic (water-fearing) tails.
* Cholesterol: A steroid essential for building cell membranes and producing hormones.
Proteins:
* Insulin: A hormone that regulates blood sugar levels.
* Hemoglobin: The protein in red blood cells that carries oxygen throughout the body.
* Antibodies: Proteins that help fight off infections by binding to foreign substances.
* Enzymes: Biological catalysts that speed up chemical reactions in the body.
Nucleic Acids:
* DNA (Deoxyribonucleic Acid): Carries the genetic code for building and maintaining an organism.
* RNA (Ribonucleic Acid): Plays a crucial role in protein synthesis, translating the genetic code from DNA into proteins.
Other Examples:
* Methane (CH4): The simplest organic molecule, a major component of natural gas.
* Ethanol (C2H5OH): The alcohol found in alcoholic beverages.
* Acetic acid (CH3COOH): The main component of vinegar.
Key features of organic molecules:
* Carbon backbone: Almost all organic molecules have a carbon backbone, with hydrogen atoms attached.
* Covalent bonds: Organic molecules are held together by strong covalent bonds, which share electrons between atoms.
* Functional groups: These are specific groups of atoms that give organic molecules their unique properties and reactivity.
