They are referred to as “inorganic” HCO3- Na2HCO3 CO CO2 Oxides of carbon Hydrogen carbonates CO32- CaCO3 Na2CO3 Carbonates Not all compounds that contain carbon are considered “organic”. Organic compounds contain carbon and are found in living organisms. Three of the four classes of life’s organic molecules are polymers.Polymer - long molecule consisting of many similar building blocks called monomers.Molecular structure and function are inseparableĬoncept 5.1: Macromolecules are polymers, built from monomers.Macromolecules - large molecules of thousands of covalently connected atoms.All living things are made up of four classes of large biological molecules:. ![]() Carbohydrates, Lipids, & Proteins Topic 3.2
