Nitrogen. Look at the structure of a peptide bond which connects each amino acid together. That is where the nitrogen is located
Nitrogen is found in proteins but not in carbohydrates and lipids
Carbohydrates and lipids.

Proteins, carbohydrates, and lipids
The four major macromolecules are proteins, carbohydrates, lipids, and nucleic acids.
Nitrogen is found in proteins but not in carbohydrates and lipids
Phosphorus complexes are present in proteins but is not present in sugars or fats..
The key element found in all carbohydrates, lipids, proteins, and nucleic acids is carbon. Carbon's ability to form four covalent bonds enables it to create complex molecules essential for life, including the diverse structures and functions of these macromolecules. In addition to carbon, hydrogen and oxygen are also commonly found in carbohydrates and lipids, while nitrogen and phosphorus are present in proteins and nucleic acids, respectively.
The element that is present in proteins but not in lipids is nitrogen. Proteins are composed of amino acids, which contain nitrogen in their amine groups, while lipids primarily consist of fatty acids and glycerol, which do not include nitrogen in their structures. This nitrogen presence is crucial for the formation of the peptide bonds that link amino acids together in proteins.
Proteins are nitrogen based while carbohydrates and lipids are not.
They have Nitrogen in them But some carbohydrates and lipids have N
