Secondary Structure of Protein
- peptide backbone has polar groups
capable of hydrogen bonding
- C=O
- N-H
- must form hydrogen
bonds for stability
- C=O
- alpha helix
- right-handed helix
- 3.6 amino acids per turn
- globular protein = 10 residues
- proline breaks helices
- peptide bonds do not
have free rotation
- right-handed helix
- Beta-pleated sheet
- bonding between adjacent chains
involves C=O and N-H groups
- adjacent chains can be
parallel or antiparallel
- bonding between adjacent chains
involves C=O and N-H groups
- Connecting loops
- alpha helices and beta sheets
are connected by loop regions
- alpha helices and beta sheets
are connected by loop regions
