The versatility of this magnetic manipulative set enables you to demonstrate the four levels of protein folding in three-dimensions. Build an alpha helix on your chalkboard or whiteboard with the layers built in 3-D. This realistic representation clarifies any student misconceptions of protein folding. Using the same polypeptide chains produced in the protein folding, you can then demonstrate the induced fit model, enzyme substrate complex, denatured proteins, active sites, allosteric sites, as well as competitive and non competitive inhibitors. The kit contents reveal how the same molecules are used repeatedly to build simple to complex structures in different biological processes.
