 What is Insulin?

Pancreatic Islet Cells secrete insulin. Without insulin, you can eat lots of food and actually be in a state of starvation since many of our cells cannot access the calories contained in the glucose very well without the action of insulin. This is why Type 1 diabetics who do not make insulin can become very ill without insulin shots. Insulin is a necessary hormone. Those who develop a deficiency of insulin must have it replaced via shots or pumps (Type 1 Diabetes). More commonly, people will develop insulin resistance (Type 2 Diabetes) rather than a true deficiency of insulin. In this case, the levels of insulin in the blood are similar or even a little higher than in normal, non-diabetic individuals. However, many cells of Type 2 diabetics respond sluggishly to the insulin they make and therefore their cells cannot absorb the sugar molecules well. This leads to blood sugar levels which run higher than normal. Occasionally Type 2 diabetics will need insulin shots but most of the time other methods of treatment will work.

Pancreas Secretes Insulin was the first hormone identified (late 1920's) which won the doctor and medical student who discovered it the Nobel Prize (Banting and Best). They discovered insulin by tying a string around the pancreatic duct of several dogs. When they examined the pancreases of these dogs several weeks later, all of the pancreas digestive cells were gone (died and were absorbed by the immune system) and the only thing left was thousands of pancreatic islets. They then isolated the protein from these islets international cargo shipping behold, they discovered insulin. Note that there are other hormones produced by different types of cells within pancreatic islets (glucagon, somatostatin, etc) but insulin is produced in far greater amounts under normal conditions making the simple approach used by Banting and Best quite successful.
