The Short Answer

Insulin is a hormone which regulates sugar (glucose) levels in the bloodstream. With another hormone called glucagon, it keeps sugar levels in the bloodstream at a nearly constant level by breaking down or building up glycogen stored in the liver or sometimes fat or protein stored elsewhere. Having glucose in the bloodstream is important because cells use it to generate energy. In a process called cellular respiration, they use the energy in the sugar to make a substance called ATP, which is used to preform many functions around the cell which require energy. Insulin also functions in diabetes, which is probably what you were looking for, but I don't know very much about that.
