DEFINITION

Classification: 514/3

Insulin or derivative:

(under subclass 2) Subject matter identical to the extract of the pancreas, known as insulin or a derivative thereof, in which neither a peptide chain nor a disulfide link between chains is broken.

(1) Note. While the position and/or kind of amino acids in the chain(s) may vary (depending on the animal from which derived), it appears that insulin contains at least an "A" chain of 21 acid units linked by disulfide moieties to a "B". An additional disulfide moiety bridges the 6 and 11 positions of chain A.
