"Sugar" usually means sucrose which contains both glucose and fructose. They do have very different effects and fructose is much worse. But in the majority of products you find both together. Glucose (aka dextrose) is much less sweet and used in things like energy drinks. Fructose on its own is more sweet than sucrose and used in "naturally light" products (same sweetness, few calories, no artificial sweeteners). But in an average intake you're going to find glucose and fructose in roughly equal amounts, I think.
