Insulin signal transduction pathway is secreted after glucose enters the beta cell and that triggers several other processes in a chain reaction. While insulin is secreted by the pancreas to lower blood glucose levels, glucagon is secreted to raise blood glucose levels. This is why glucagon has been known for decades as a counter-regulatory hormone. When blood glucose levels are low, the pancreas secretes glucagon, which in turn causes the liver to convert stored glycogen polymers into glucose monomers, which is then released into the blood. This process is called glycogenolysis. Liver cells, or hepatocytes, have glucagon receptors which allow for glucagon to attach
Insulin aspart be used with external insulin pumps. The insulin in reservoirs of insulin pumps and infusion sets should be changed every 48 hours to avoid insulin degradation and loss of preservative. The following insulin pumps have been used in Novolog® clinical or in vitro studies conducted by Novo Nordisk: Medtronic Paradigm® 512 and 712, Minimed 508, Disetronic® D-TRON® and H-TRON®. NovoLog Mix 70/30 is a product marketed by Novo Nordisk which contains 30% insulin aspart and 70% insulin aspart protamine. The insulin aspart protamine portion is a crystalline form of insulin aspart, which delays the action of the insulin, giving it
