The four types of organic compounds are carbohydrates, lipids, proteins and nucleic acids. Organic molecules contain the elements carbon and hydrogen, and they are found and made in living things. Keep Learning.
These elements exist in the form of molecules and organelles â picture them as the tools, appliances, and inner rooms of the cell. Major classes of intracellular organic molecules include nucleic acids, proteins, carbohydrates, and lipids, all of which are essential to the cell's functions. Nucleic acids are the molecules that contain and help express a cell's genetic code. There are two major classes of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
