Figure 1
(a) The chemical structure of L-cysteine in its zwitterionic form. Displacement ellipsoid plots showing numbering schemes for (b) L-cysteine-I (at ambient pressure and ambient temperature), (c) L-cysteine-III and (d)/(e) L-cysteine-IV. All displacement ellipsoids are drawn at 30% probability. Note (d) and (e) are referred to in the text as molecules 2 and 1, respectively.
