Detailed explanation-1: -The elements that make up proteins are carbon, hydrogen, oxygen as well as nitrogen .

Detailed explanation-2: -In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.

Detailed explanation-3: -Proteins contain the elements carbon, hydrogen, and oxygen just as carbohydrates and lipids do, but proteins are the only macronutrient that contains nitrogen. In each amino acid the elements are arranged into a specific conformation around a carbon center.

Detailed explanation-4: -Proteins contain carbon, hydrogen, oxygen, nitrogen, and sulfur. Protein molecules consist of one or more chains of small molecules called amino acids. The sequence of amino acids in chains and the number of chains in a protein determine the protein’s shape.

Detailed explanation-5: -Amino acids join to form proteins. Each amino acid is formed with one basic group NH2 and one acidic group(COOH).
