Quizplus · Accepted Answer

Amino acids are the building blocks of protein molecules. They are linked together through peptide bonds to form polypeptide chains that fold into functional protein molecules. While nucleic acids also contain nitrogen-containing bases that are derived from amino acids, they are ultimately composed of nucleotides rather than amino acids. Therefore, amino acids are primarily used for building protein molecules in the body.
