Detailed explanation-1: -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-2: -All proteins contain four elements, carbon, hydrogen, oxygen and nitrogen, with most proteins also containing sulfur. Further, there are proteins which also contain phospho-rus, iodine, iron, copper and zinc. These elements are contained in the proportions shown below, with percentages varying in each protein.
Detailed explanation-3: -The arrangement of amino acids along the chain determines the structure and chemical properties of the protein. Amino acids consist of the following elements: carbon, hydrogen, oxygen, nitrogen, and, sometimes, sulfur.
