(1) Note. The presence of the term dipeptide is not dispositive although it should alert the user to the possibility of classification in this subclass.
(2) Note. Caution should be observed in search for compounds denominated as dipeptides or containing a single peptide bond between an amino acid and another moiety or a peptide bond connecting complex heterocyclic compounds. Such compounds should be searched as if this subclass did not exist.
(3) Note. Dipeptide. Compounds denominated dipeptides have been placed in this subclass and its indents as a search aid. The patents in these subclasses have been otherwise placed as if these subclasses did not exist.
