Students explore the shape and chemical properties of the 20 amino acid sidechains with engaging plastic models. The sidechains feature dual coloring schemes – color on the plastic clip indicates chemical properties, while the individual atoms of the sidechains are colored by atom type. Since understanding protein structure begins with this unique combination of shape and chemical properties of the amino acid sidechains, students will gain a basic knowledge of the laws that determine protein folding.
Protein folding is influenced by several factors, one of which is the chemical properties of the amino acid sidechains. Through this exercise, students will explore the chemical properties that dictate the way a protein will fold. A flexible, foam-covered wire represents the backbone of the peptide to which the plastic sidechains are attached.
