The pancreas is a large gland located behind the stomach. One of the functions of the pancreas is to produce two hormones: insulin and pancreatic polypeptide. Insulin helps the cells to take in glucose. The liver makes glucose and insulin normally acts to decrease or shut off the liver's production of glucose. N2 - This chapter discusses the mode of action and biological functions of the ubiquitin system. Ubiquitin is a small polypeptide present in apparently all eukaryotic cells. It was originally isolated in the characterization of polypeptide hormones of the calf thymus.

What is this test? This test measures a substance in your blood called pancreatic polypeptide. Pancreatic polypeptide is secreted by special cells in your pancreas. People who have neuroendocrine tumors (NETs) have higher levels of this substance. These tumors can be functional or nonfunctional. Nonfunctional tumors are more common. Peptide hormones tend to have very short half-lives within the circulation, which allows blood levels to change rapidly in response to changes in secretion. Like the rapid changes in secretion and blood concentrations, initiation of signaling tends to be rapid, which is facilitated by high on rates for hormone binding to receptors. Pancreatic hormones help in maintaining constant blood glucose levels, storage of carbohydrates and fats into glycogen after meals and the mobilization of energy by the breakdown of glycogen.
