검증된 단계별 안내1
Identify the primary composition of each substance listed in the problem.
Understand that proteins are composed of amino acids linked by peptide bonds.
Recognize that hemoglobin, collagen, and keratin are all proteins, each with specific functions in the body.
Recall that cellulose is a polysaccharide, which is a carbohydrate, not a protein.
Conclude that cellulose is the substance not primarily composed of protein, as it is made up of glucose units linked by β-1,4-glycosidic bonds.
