Insulin+&+Glucagon

1. Structure - (See Above) Insulin and glucagon are secreted in the Pancreas. Both are diffused into the blood stream (pancreaticcancersyndroms.com) 2. Function - Insulin and glucagon work together to keep blood sugar levels in tandem within the body. When blood sugar is too low, glucagon will convert stored glycogen into glucose as usable energy. Conversly, the hormone insulin, functions to transform glucose into glycogen to lower blood sugar levels. Both of these ihormones are negative feed back loops in that when they reach a certain blood sugar level, that level turns of the hormones function (reading). 3. Diseases associated with insulin and glucagon are far from rare. To inability to produce insulin, or diabetes, can often result in the necessity of injected insulin.In terms of diabetes, there are two types. Type 1 diabetes is genetic and causes an inabiliy to create sufficient insulin to lower the blood sugar in the body. Type 2 diabetes is late onset diabetes, in which lack of exercise and poor eating habits, cause a malfunction that disallows the pancreas to secrete insulin. More rarely, cancer of alpha cells in glucagon can causes a cancer known as glucaganomas (colostate.edu). 4. Topic number #16
