How did Banting and Best discover insulin?
Banting came up with a way to extract pancreatic extract in 1921; John MacLeod, the head of physiology at The University of Toronto, oversaw this process; Charles Best, Banting’s assistant, helped refine the process, and a biochemist named James Collip helped to purify insulin even further to make it clinically useful.
What is the significance of the discovery of insulin by Frederick Banting and Charles Best?
Arguably one of Canada’s greatest contributions in the area of medical research, the discovery of insulin completely transformed the treatment of diabetes, saving millions of lives worldwide.
Who is the father of insulin?
Sir Frederick G Banting
Insulin was discovered by Sir Frederick G Banting (pictured), Charles H Best and JJR Macleod at the University of Toronto in 1921 and it was subsequently purified by James B Collip. Before 1921, it was exceptional for people with type 1 diabetes to live more than a year or two.

Who were Banting and Best?
In the early 1920s Frederick Banting and Charles Best discovered insulin under the directorship of John Macleod at the University of Toronto. With the help of James Collip insulin was purified, making it available for the successful treatment of diabetes. Banting and Macleod earned a Nobel Prize for their work in 1923.
Is insulin still made from pigs?
Insulin was originally derived from the pancreases of cows and pigs. Animal-sourced insulin is made from preparations of beef or pork pancreases, and has been used safely to manage diabetes for many years. With the exception of beef/pork insulin, which is no longer available, they are still being used safely today.
