Research on carbohydrate metabolism
Macleod studied medicine at Aberdeen and worked in Leipzig, London and the United States before becoming Toronto’s Professor of Physiology in 1918. His earlier investigations of carbohydrate metabolism and experimental glycosuria supplied experience relevant to the pancreatic-extract project.

Laboratory support and collaboration
Macleod supported Banting and Best’s use of experimental facilities and helped assess and develop the research. With Collip’s purification work, the project advanced toward clinical use and production. Institutional biographies of Best and Collip document their respective contributions to preparation, purification and supply.
Recognition and return to Aberdeen
Macleod shared the 1923 Nobel Prize with Banting and announced that he would share his prize money with Collip. Returning to Aberdeen in 1928, he continued physiological research and teaching until his death in 1935. The two prize recipients represented a larger research collaboration.
