Insulin oscillation blood from the pancreas to the liver, which is a major insulin target. Disturbances of the insulin oscillations occur early in type 2 diabetes and may contribute to insulin resistance. Pulsatile insulin delivery to the portal vein or islet cell transplantation to the liver of diabetic patients are therefore attractive therapeutic alternatives. Insulin oscillation The insulin concentration in blood increases after meals and gradually returns to basal levels during the next 1–2 hours. However, the basal insulin level is not stable. It oscillates with a regular period of 3-6 min. After a meal the amplitude of these oscillations increases but
Insulin analog Insulin analog An insulin analog is an altered form of insulin, different from any occurring in nature, but still available to the human body for performing the same action as human insulin in terms of glycemic control. Through genetic engineering of the underlying DNA, the amino acid sequence of insulin can be changed to alter its ADME (absorption, distribution, metabolism, and excretion) characteristics. Officially, the U.S. Food and Drug Administration (FDA) refers to these as "insulin receptor ligands", although they are more commonly referred to as insulin analogs. These modifications have been used to create two types of insulin analogs:
