Understand that proteins are large, complex molecules that play many critical roles in the body. They are made up of smaller units called monomers.
Identify the monomer units that combine to form proteins. These are known as amino acids.
Recognize that amino acids are organic compounds composed of an amino group (-NH2), a carboxyl group (-COOH), and a unique side chain (R group) that defines each amino acid.
Learn that there are 20 different amino acids that can be combined in various sequences to form a vast array of proteins, each with unique functions and structures.
Differentiate between amino acids and other biological monomers such as monosaccharides (which form carbohydrates), fatty acids (which form lipids), and nucleotides (which form nucleic acids).
