Verified step by step guidance

Step 1: Understand the question. The problem is asking which macromolecule is composed of amino acids as its monomeric units. Amino acids are small organic molecules that serve as building blocks for a specific type of macromolecule.

Step 2: Recall the structure and function of macromolecules. Polysaccharides are composed of monosaccharides (sugar units), lipids are composed of fatty acids and glycerol, nucleic acids are composed of nucleotides, and proteins are composed of amino acids.

Step 3: Focus on proteins. Proteins are macromolecules formed by the polymerization of amino acids through peptide bonds. This process creates polypeptide chains, which fold into functional three-dimensional structures.

Step 4: Eliminate incorrect options. Polysaccharides, lipids, and nucleic acids do not use amino acids as their monomeric units. Proteins are the correct answer because they are directly composed of amino acids.

Step 5: Conclude that proteins are the macromolecule composed of amino acids as their monomeric units, based on their structure and function in biological systems.
