Proline is referred to as the "helix breaker" because
A)its only found in the L form,which is incompatible with helical protein structure.
B)it lacks the hydrogen atom needed for hydrogen bonding.
C)it lacks a charged functional groups for ionic bonding.
D)it is hydrophobic.
E)it has a polar functional group.
