(a) Corrugated interconnected sheets of amino acids in the DL-lysine complex. O, N and C atoms are indicated by circles of decreasing size. Only atoms which make hydrogen bonds are labelled. Hydrogen bonds are indicated by broken lines. The same convention is also used in the subsequent figures. (b) Arrangement of hydrogen-bonded ribbons of semi-glutarate ions in the DL-lysine complex. |
