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.
This article covers the main categories of naturally occurring organic macromolecules: carbohydrates, proteins, nucleic acids and lipids. disaccharide made of glucose and galactose. is that organic molecules contain carbon-hydrogen bonds, whereas inorganic molecules do not. The four major classes of organic molecules include carbohydrates, proteins, lipids and nucleic acids. Carbohydrates The term carbohydrate is actually a descriptor of what these molecules are composed of; carbon hydrates, in a ratio of one carbon molecule to one water molecule (CH2O)n.
