The discovery of insulin is a milestone in the history of modern medicine. In the early 20th century, some doctors found that extracts from the pancreas had a hypoglycemic effect. However, due to the inability to prepare high-purity preparations, the relevant research was once in trouble. In 1920, young surgeon Frederick Banting proposed to John McLeod, an authoritative professor in the field of diabetes, a way to purify insulin. Banting suggests ligation of the dog's pancreatic duct and its separation and extraction. The purification of insulin has been since then. By 1921, Banting's source of insulin had shifted from the dog's pancreas to the cow's embryo, giving the experiment a leap forward. In 1923, banting and mclade won the nobel prize in physiology and medicine for their contribution to insulin.
