When did Fredrick Banting invent insulin?

In 1921, Canadian scientists Frederick Banting and Charles Best successfully isolated and purified insulin, a hormone produced by the pancreas that regulates blood sugar levels. Before this discovery, people with diabetes were often forced to severely restrict their food intake or face life-threatening complications. Insulin proved to be a life-saving breakthrough, and in 1923, Banting and Best were awarded the Nobel Prize in Medicine for their work. Their discovery not only revolutionized the treatment of diabetes but also paved the way for future advancements in the field of hormone research and treatment.
