Primary Structure of Proteins
- made up of polypeptide chains
- 5000 amino acids linked together
- 20 different amino acids
- neutral solution = zwitterionic
- + charge on nitrogen atom
- negative charge
on carboxyl group
- all amino acids = same general structure
- except proline
- all amino acids = have the L configuration
- except glycine
- peptide bond = loss of water molecule
- N-terminal end has NH3+ group
- other end = carboxyl group
