Insulin was the first peptide hormone discovered. [17] Frederick Banting and Charles Best, working in the laboratory of John Macleod at the University of Toronto, were the first to isolate insulin from dog pancreas in 1921. Frederick Sanger sequenced the amino acid structure in 1951, which made insulin the first protein to be fully sequenced. [18]
Sir Frederick Grant Banting (November 14, 1891 – February 21, 1941) was a Canadian pharmacologist, orthopedist, and field surgeon. [3] For his co-discovery of insulin and its therapeutic potential, Banting was awarded the Nobel Prize in Physiology or Medicine with John Macleod.
Insulin was first used as a medication in Canada by Charles Best and Frederick Banting in 1922. [85] [86] This is a chronology of key milestones in the history of the medical use of insulin. For more details on the discovery, extraction, purification, clinical use, and synthesis of insulin, see Insulin

The determination of the amino acid sequence of insulin (by Sir Frederick Sanger, for which he received a Nobel Prize). Insulin was the first protein that the amino acid structure was determined.

Charles Herbert Best (February 27, 1899 – March 31, 1978), was an American-Canadian medical scientist and one of the co-discoverers of insulin with Frederick Banting.He served as the chair of the Banting and Best Department of Medical Research at the University of Toronto and was further involved in research concerning choline and heparin.
Nicolae Constantin Paulescu (Romanian pronunciation: [nikoˈla.e pa.uˈlesku]; 30 October 1869 (O.S.) – 17 July 1931) was a Romanian physiologist, professor of medicine, and politician, most famous for his work on diabetes, including patenting pancreine (a pancreatic extract containing insulin).
From Banting's viewpoint, "this was a brazen coup by Macleod to rob him of the credit for having discovered insulin – and to rub salt into the wound, it had been done in front of the most eminent doctors in the field". [14] Their discovery was first published in the February 1922 issue of The Journal of Laboratory and Clinical Medicine. [15]
