What is the isoelectric point?
The pH at which an amino acid is neutrally charged
What is a zwitterion
A molecule that carries a negative and positive charge simultaneously
What is unique about proline giving it the ability to disrupt secondary protein structure?
Proline has a secondary alpha amino group which causes it to introduce kinks into the alpha helix structure
Which Amino Acid does not have an S configuration
