Onset is the length of time before insulin reaches the bloodstream and begins lowering blood glucose.
Peaktime is the time during which insulin is at maximum strength in terms of lowering blood glucose.
Duration is how long insulin continues to lower blood glucose.
Insulin has several broad actions including:
It causes the cells in the liver, muscle, and fat tissue to take up glucose from blood and convert it to glycogen that can be stored in the liver and muscles
Insulin also prevents the utilization of fat as an energy source. In absence of insulin or in conditions where insulin is low glucose is not taken up by body cells, and the body begins to use fat as an energy source
Insulin also controls other body systems and regulates the amino acid uptake by body cells
It has several other anabolic effects throughout the body as well * Shakiness, dizziness or lightheadedness, sweating, nervousness or irritability, sudden changes in behavior or mood, headache, numbness or tingling around the mouth, weakness, pale skin, hunger clumsy or jerky movement
Insulin comes as a solution (liquid) and a suspension (liquid with particles that will settle on standing) to be injected subcutaneously (under the skin). Insulin is usually injected several times a day, and more than one type of insulin may be needed.
Insulin comes in vials, pre-filled disposable dosing devices, and cartridges
* Humulin R® * Humulin N® * Humulin 70/30® * Humulin 50/50® * Humulin R U-500® * Novolin R® * Novolin N® * Novolin 70/30®
Always look at your insulin before you inject. If you are using a regular insulin (Humulin R, Novolin R), the insulin should be as clear, colorless, and fluid as water.
Insulin was the first protein ever to have its sequence determined. The exact sequence of amino acids comprising the insulin molecule was found by British molecular biologist Frederick
