What are the molecules in corn syrup?

The main molecules in corn syrup are glucose and fructose. Glucose is a simple sugar that the human body can easily digest and use for energy. Fructose is a slightly sweeter sugar that the body takes longer to digest. In corn syrup, the ratio of glucose to fructose is typically 42:53. In addition to these two sugars, corn syrup also contains small amounts of other molecules, such as water, maltose, and dextrin.
