Answer: Proteins and nucleic acids
Which of the four types of organic molecules contain the element nitrogen?

For historical reasons discussed below a few types of carbon-containing compounds such as carbides carbonates (excluding carbonate esters) simple oxides of carbon (for example CO and CO2) and cyanides are considered inorganic. Different forms (allotropes) of pure carbon such as diamond graphite fullerenes and carbon nanotubes are also excluded because they are simple substances composed of only a single element and therefore are not generally considered to be chemical compounds.

Organic chemistry is a branch of chemistry that studies the structure properties and reactions of organic compounds which contain carbon in covalent bonding. Study of structure determines their chemical composition and formula. Study of properties includes physical and chemical properties and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products drugs and polymers and study of individual organic molecules in the labor…
