Amino Acid Groups
5 properties (structural) |
1) Nonpolar
often have (-CH2) or (-CH3) Ala, Val, Leu, Ile 2) Polar Uncharged R groups contain O (or only --H) ex) Gly, Ser, Thr, Asn, Gln 3) Charged have R groups that contain Acids or Bases Glu, Asp, His, Lys, Arg 4) Aromatic R groups contain an organic (Carbon) ring with alternating single/double bonds. ex) Phe, Trp, Tyr 5) Special-Function Unique properties Methionine -often 1st in chain Proline-causes kinks in chains Cysteine- links chains toget. |
