What did Banting discover?

Discovered insulin, which is closely related to diabetes

Diabetes is a disease that increases the amount of sugar in the blood (blood glucose level), and in the past it was thought to be a disease that could never be cured.

Banting believed that diabetes was caused by a lack of substances that are supposed to be produced by the body. Through intense research, he succeeded in discovering the cause of diabetes and its cure, insulin.

Thanks to Banting's discovery, millions of diabetics have been saved.

Insulin is a very important discovery! Diabetes is a disease in which sugar in the blood (blood glucose level) rises because the body does not properly break down the sugar obtained from food and other sources.
The discovery of insulin as a substance that lowers blood glucose levels was considered one of the greatest advances in medicine at the time, and within a year or two it was being mass-produced.
Within a year or two, insulin was being mass-produced, and as many as five researchers were awarded the Nobel Prize in recognition of their achievements in insulin research and development.

How did Banting discover insulin?

One day, Banting, who was working as a research assistant at a university, was doing research to prepare for a class. One day, while doing research in preparation for a class, he came across a research article in a journal.
It stated that "when the pancreatic ducts become blocked, digestive juices cease to flow. Reading this, Banting thought that he might be able to extract an "unknown substance" that could cure diabetes from the pancreas, which does not produce digestive juices.
Banting continued his research and experiments and came up with a method to extract an unknown substance, insulin, from the pancreas.

Discovery of an Unknown Substance by Stopping the Pancreatic Tube Until now, no one had been able to discover "unknown substances" because the substances were destroyed by the digestive juices produced by the pancreas.
Banting then constricted the tube connecting the pancreas and the duodenum to prevent the pancreas from producing digestive juices. This idea led to the brilliant discovery of an unknown substance: insulin.

Is it true that Banting was very worried about becoming a researcher?

Banting saved many diabetics and was awarded the Nobel Prize. However, before discovering insulin, Banting did not have a sufficient income, so he was assigned to work as a doctor with a research team drilling for oil in the Arctic.
However, due to various circumstances, he no longer needed to accompany the expedition. Therefore, I decided to pursue research at a university, which was another path I was considering at the same time.
If Banting had accompanied the research team, the discovery of insulin might never have been made.

Doctor or Researcher, Fate is Determined by a Coin! One day, Banting was torn between working as a doctor accompanying an oil exploration team and earning a living, or becoming a university researcher and devoting himself to research.
When he tossed a coin, he decided to go to "Research" if the coin came up "Heads" and "Arctic" if the coin came up "tails". The result was "Arctic" on the flip side.
However, the offer to accompany him to the North Pole disappeared, and Bunting went on to become a researcher.
