Insulin and form fibrillar interdigitated beta-sheets. This can cause injection amyloidosis, and prevents the storage of insulin for long periods. Insulin is produced in the pancreas and the Brockmann body (in some fish), and released when any of several stimuli are detected. These stimuli include ingested protein and glucose in the blood produced from digested food. Carbohydrates can be polymers of simple sugars or the simple sugars themselves. If the carbohydrates include glucose, then that glucose will be absorbed into the bloodstream and blood glucose level will begin to rise. In target cells, insulin initiates a signal transduction, which has the
Insulin (medication) shown no unequivocal advantages in clinical use of insulin analogues over more conventional insulin types. Choosing insulin type and dosage/timing should be done by an experienced medical professional working closely with the diabetic patient. The commonly used types of insulin are as follows. Includes the insulin analogues "aspart", "lispro", and "glulisine". These begin to work within 5 to 15 minutes and are active for 3 to 4 hours. Most insulins form hexamers, which delay entry into the blood in active form; these analog insulins do not but have normal insulin activity. Newer varieties are now pending regulatory approval in the
