Science Past from the issue of December 29, 1962

INSULIN SYNTHESIS SEEN — Synthesis of insulin for the first time may be realized early in 1963…. Dr.  Panayotis G. Katsoyannis [of the University of Pittsburgh] is hopeful  that the last problems are about to be  solved in synthesis of the life-saving protein-hormone important to  diabetic patients. Chinese scientists, either  in Shanghai or Peking, are believed to be working on the insulin-B chain containing  30 amino acid molecules that when joined with the A chain (containing 21 amino acid molecules) will produce  insulin.
