Protein lab

1) the bond is found between the amino acids in the primary structure is peptide bond.

2) the secondary structure forms a alpha helix because the (-) and the (+) attracts causing them to form a alpha helix from the peptide bonds. 

3) the repulsion and covalent bonds created the third structure when the protein was twisted and bent. It looked different because there are 20 different variables which can make different combinations. 

4) the fourth structure was created when two or more amnio acids and the variables repelled or attracted. 

5) the protein would not have the same shape if the primary structure was changed because the R group attraction and repulsion determines it.
