Pharmacologists study the actions of drugs in the intestinal tract, the brain, the muscles, and the liver-just a few of the most common areas where drugs travel during their stay in the body. Of course, all of our organs are constructed from cells, and inside all of our cells are genes.
Insulin has several broad actions including: 1  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. 2  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. 2  Insulin also controls other body systems and regulates the amino acid uptake by body cells. 3  It has several other anabolic effects throughout the body as well.
