Unformatted text preview: which it belongs (you do not have to memorize the structures, but you should be able to put the specific amino acids into the correct group by name). Ok. 4. Draw an amino acid, draw a dipeptide. If given a specific pH, be able to draw the appropriate ionization state of the amino and carboxyl groups of the amino acids. In notebook. 5. Compare and contrast the structures of β-pleated sheets and α helices. Both have H-bonds, both secondary structures, different folding β-pleated sheets- between 2 stands-can be anti or parallel, H bonds further down α helices-shorter, closer 6. Illustrate the hydrogen bonding observed in secondary structures of proteins. H-bonding between amino acids Alpha helices bond N-O peptide between same strands Beta sheets bond N-O peptide between different strands...
