Insulin (medication) cover meals (bolus also known as mealtime or prandial insulin). Maintaining the basal rate and the bolus rate is a continuous balancing act that people with insulin-dependent diabetes must manage each day. This is normally achieved through regular blood tests, although continuous blood sugar testing equipment (Continuous Glucose Monitors or CGMs) are now becoming available which could help to refine this balancing act once widespread usage becomes common. A long-acting insulin is used to approximate the basal secretion of insulin by the pancreas, which varies in the course of the day. NPH/isophane, lente, ultralente, glargine, and detemir may be used
Insulin in the various signaling pathways by tyrosine phosphatases. Serine/Threonine kinases are also known to reduce the activity of insulin. The structure of the insulin–insulin receptor complex has been determined using the techniques of X-ray crystallography. The actions of insulin on the global human metabolism level include: The actions of insulin (indirect and direct) on cells include: Insulin also influences other body functions, such as vascular compliance and cognition. Once insulin enters the human brain, it enhances learning and memory and benefits verbal memory in particular. Enhancing brain insulin signaling by means of intranasal insulin administration also enhances the acute thermoregulatory
