nitrogen
Proteins contain nitrogen, which is not present in carbohydrates.
CHON (carbon, hydrogen, oxygen, nitrogen).
Nitrogen.
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.
Nitrogen is found in proteins but not in carbohydrates and lipids
None. They all have carbon and hydrogen in common. Proteins also contain nitrogen, but so do many lipids (for example phosphatidylcholine).
Carbon, hydrogen, and oxygen. Carbohydrates have a ratio of CHO of 1:2:1. Fats have CHO but with a different ratio. Proteins have CHO and nitrogen.
Nitrgen. The all have the elements Carbon, Hydrogen and Oxygen in common, but on top of that, proteins ALSO contain nitrogen.
You shouldn't find nitrogen or sulphur in carbohydrates. Carbohydrates only contain carbon, hydrogen and oxygen.

Sulfur, Phosphorus, oxygen, nitrogen, hydrogen and carbon are the six elements that join together to form proteins, carbohydrates, lipids, ATP and nucleic acids.
