Detailed explanation-1: -Proteins are found in all living organisms and are composed of molecules called amino acids. Each amino acid contains four elements they are hydrogen, oxygen, nitrogen and carbon and in certain cases may also contain sulfur.

Detailed explanation-2: -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-3: -Proteins are compounds composed of carbon, hydrogen, oxygen, and nitrogen, which are arranged as strands of amino acids . They play an essential role in the cellular maintenance, growth, and functioning of the human body.

Detailed explanation-4: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

Detailed explanation-5: -Amino acids (AA) are quaternary compounds of carbon, hydrogen, oxygen and nitrogen and are the basic components of human proteins.
