Lending Library Update
Due to the COVID-19 pandemic, the MSOE Model Lending Library has suspended operations. Before reopening, we need to identify safe ways of disinfecting library materials between uses. We hope to have decisions made by mid-July about which materials will be available for loan in the fall.
The linear amino acid sequence defines the primary structure of a protein. Regions of the linear polypeptide chain fold into the stable α-helix and β-sheet structures to form the protein secondary structure. The tertiary protein structure is the overall three-dimensional shape of the protein. With this model collection, students can assemble an α-helix or anti-parallel β-sheet, compare the phi-psi angles of the two secondary structures, and explore the contribution of hydrogen bonding to the stability of the structure. Models of the α-helix and β-sheet, with and without side chains, allow comparison of the features of the two secondary structures. Two protein models display tertiary protein structure. The β-globin protein consists predominantly of α-helices while the green fluorescent protein (GFP) consists predominantly of a β-sheet.
Models in the Collection
- α-helix without sidechains
- α-helix with sidechains
- β-sheet without sidechains
- β-globin protein
- Green fluorescent protein (GFP)
- 6 α-Helix β-Sheet Construction Kits

Requesting Other Models
You may schedule one copy of a model for three weeks. Due to limited resources, we are unable to loan multiple copies or additional materials.
If you would like to request a loan of a different model for the same time frame you may add this to your cart. Up to three different types of models may be checked out at one time. You will need to fill out a separate request for model loans with a different time frame.
Please contact us at firstname.lastname@example.org with any questions about the lending process or the availability of models.
