Detailed explanation-1: -Proteins are different from fats and carbohydrates due to the presence of nitrogen, carbon, hydrogen, and oxygen in them. Carbohydrates only contain carbon, hydrogen, and oxygen whereas fats contain fatty acids which contain a carboxyl group and an alkyl group, thus containing only carbon, oxygen, and hydrogen.
Detailed explanation-2: -Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).
Detailed explanation-3: -Proteins differ from carbohydrates and lipids in that, they always contain nitrogen, carbon, hydrogen and oxygen.
Detailed explanation-4: -The chemical structure of proteins contain carbon, hydrogen, oxygen, and nitrogen, while the chemical structures of carbohydrates and fats contain only carbon, hydrogen, and oxygen. Carbohydrates and fats do not contain nitrogen while protein does contain nitrogen.
