The primary element found in organic compounds is carbon. Organic compounds are characterized by the presence of carbon atoms, usually bonded with hydrogen, oxygen, nitrogen, sulfur, and phosphorus. Carbon's unique ability to form four covalent bonds allows it to create a vast array of complex structures, such as chains and rings, which are essential for the diversity of life. This versatility makes carbon the backbone of biological molecules, including carbohydrates, proteins, lipids, and nucleic acids. The study of these compounds is vital in fields such as biochemistry, molecular biology, and organic chemistry, as they are foundational to understanding living organisms.
