The correct answer is Option (4)- proteins Amino acids are often referred to as the building blocks of proteins. Explanation: Proteins are large, complex molecules composed of chains of amino acids. Amino acids are organic compounds that contain an amino group (-NH2), a carboxyl group (-COOH), and a side chain specific to each amino acid. When amino acids join together through peptide bonds, they form polypeptide chains, which can then fold into complex three-dimensional structures to create proteins. The sequence and arrangement of amino acids in a protein determine its structure and function. Therefore, amino acids are crucial components for the synthesis and structure of proteins, making them the fundamental building blocks of this important macromolecule. |
