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.
It turns out, this is true. While organic chemistry is the study of molecules that contain carbon, they also contain other atoms. So, organic molecules can contain carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur. All of these atoms come together to make what we call functional groups.t turns out, this is true.
