Discription: Food -- that's energy needed by our body for our livelihoods. The most important fuel is a sugar -- the so called glucose. Glucose is most wanted -- among others by the liver, the muscles and the fat tissue. Insulin plays a central role for sugar metabolism. However in many people this process doesn't work properly. Glucose is transported through the blood stream. From there it reaches the body cells -- a process controlled by insulin. If the enzyme SGK1 is overactive it blocks the cell membrane and hence the passageway for the sugar. Insulin is now no longer of any help. Diabetes and its complications will develop.
