NEET BIOLOGY

Detailed explanation-1: -Protein consists of carbon, hydrogen, Oxygen and nitrogen elements.

Detailed explanation-2: -Nitrogen is in all amino acids and nucleotides, and therefore in all proteins and nucleic acids. Nitrogen is also a major component of the chitin that makes up the cell walls of fungi and the exoskeletons of aquatic insects and crustaceans.

Detailed explanation-3: -Just like carbohydrates and fats, proteins contain the elements carbon, hydrogen, and oxygen, but proteins are the only macronutrient that also contain nitrogen as part of their core structure.

Detailed explanation-4: -Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.

Detailed explanation-5: -Proteins are made up of many amino acid units. The amino acid units have an amino group as part of the general structure. The amino group is also known as the functional group as amine which contains a Nitrogen atom. Therefore, the amino group will have the Nitrogen atom for the protein.
