L-Amino Acid Structures

Notes: 1) loading of all molecules may take some time; 2) molecules are not all shown at the same scale

Backbones are oriented amino (left) to carboxy (right)

R-group sidechains project upward from the backbone alpha carbon

Except for the alpha carbon, the CPK atom coloring scheme is used: C, H, N, O, P, S

Name colors indicate: hydrophobic, polar (non-charged), polar (charged-basic), polar (charged-acidic)
