_chem_comp.three_letter_code

Name:
'_chem_comp.three_letter_code'

Definition:

   For standard polymer components, the three-letter code for
   the component. If there is not a standard three-letter code
   for this component, or if this is a non-polymer
   component, the three-letter code should be given as 'UNK'.
   This code may be preceded by a '+' character to indicate
   that the component is a modification of a standard
   component.
