Verified step by step guidance1
Understand that proteins are large, complex molecules that play many critical roles in the body. They are made up of smaller units called amino acids.
Recognize that amino acids are organic compounds composed of an amino group (-NH2), a carboxyl group (-COOH), and a side chain specific to each amino acid.
Identify that there are 20 different amino acids that combine in various sequences to form proteins, each with unique properties and functions.
Differentiate between amino acids and other biological molecules: nucleotides are the building blocks of nucleic acids (DNA and RNA), fatty acids are components of lipids, and monosaccharides are simple sugars that form carbohydrates.
Conclude that amino acids are the correct answer as they are the building blocks of proteins, linking together in chains to form polypeptides, which fold into functional proteins.
