Detailed explanation-1: -The elements that make up proteins are carbon, hydrogen, oxygen as well as nitrogen .
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: -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-4: -Amino acids join to form proteins. Each amino acid is formed with one basic group NH2 and one acidic group(COOH).
Detailed explanation-5: -Hydrogen atoms constitute nearly half of the atoms in proteins. They mediate hydrogen bridges and take part in the nonbonding interactions such as electrostatic and van der Waals forces.
