Which of the four types carbohydrates lipids proteins or nucleic acids contain the element nitrogen?

Among the four types of macromolecules—carbohydrates, lipids, proteins, and nucleic acids—only proteins and nucleic acids contain the element nitrogen. Proteins are made up of amino acids, which include nitrogen in their structure, while nucleic acids, such as DNA and RNA, contain nitrogenous bases that are essential for their function. Carbohydrates and lipids do not contain nitrogen in their basic structures.
