What in the World is Insulin?

While insulin is involved in these conditions, the dangers of uncontrolled levels of insulin show to be more life-threatening. Insulin is a hormone that plays an essential role in digestion and metabolism because it allows glucose to enter the body's cells to provide energy. It is also responsible for regulating the storage of excess glucose in the liver, muscles and fat cells. Driven by Canadian inventiveness in 1921 and carried across the globe, insulin is widely recognized as one of medicine's greatest achievements. In this book, you will learn the story of insulin, including its discovery, development and continued innovation.
