Proteins contain nitrogen, which is not present in carbohydrates.
The main element in protein is nitrogen. Proteins are made up of amino acids, which contain nitrogen in addition to carbon, hydrogen, and oxygen. This distinguishes proteins from carbohydrates and fats, which do not contain nitrogen.
Proteins have the most nitrogen element among the three biomolecules listed. Proteins are composed of amino acids, which contain nitrogen in their chemical structure. Both carbohydrates and lipids contain very low amounts of nitrogen in comparison.
Proteins contain a special form of nitrogen that our bodies can readily use.
Nitrogen.
Nitrogen is found in proteins but not in carbohydrates and lipids
no
Phosphorus complexes are present in proteins but is not present in sugars or fats..

Nitrgen. The all have the elements Carbon, Hydrogen and Oxygen in common, but on top of that, proteins ALSO contain nitrogen.
None. They all have carbon and hydrogen in common. Proteins also contain nitrogen, but so do many lipids (for example phosphatidylcholine).
