- Abstract
- The Amino Acid Starter Kit© allows your students to explore how the unique chemical properties of the 20 amino acids determine the final shape of a protein. Three downloadable student handouts lead your students through the hands-on protein-folding activities. Learn that the 20 amino acids all share a common backbone but have different side chains, each with different chemical properties. Identify the chemical properties of the side chains through a dual coloring scheme guided by the kit’s chemical properties circle, amino acid side chain list and colored plastic clips. Group the side chains into one of 5 categories: hydrophobic (nonpolar), hydrophilic (polar), negatively charged, positively charged, and cysteines, which sometimes form disulfide bonds. The colored clip at the base of each side chain indicates chemical properties while embedded colored balls in the amino acid side chain model show atomic structure. Employ the kit’s protein-folding activities to first explore the primary and tertiary structure of proteins by constructing a generic 15-amino acid protein, then learn about the secondary structure of proteins by folding a toober model of the first of 3 zinc fingers of the Zif268 protein.Choking hazard
