- What charge does the amino end of a polypeptide chain? What charge does the free carboxyl group have?
- What is a polypeptide, and how is it different than a protein?
- What forms the backbone of a polypeptide?
- What kind of chemical bonds does the R-group orientation of polypeptides determine its shape?
