Glucose, also known as dextrose, is one of the most famous and important organic compounds. Its molecule structures and functional groups are worth to explore because they determine the efficacy, functions, and reactivities of glucose molecule. Glucose's structure and isomers are complex, and they determine the some of the properties of glucose molecule. Our prediction of glucose's reactivity suggests that glucose's chemical property has a close relation with the function groups it contains. There are various methods to synthesis glucose, including photosynthesis and extraction. Organisms' blood contains glucose; thus, glucose is a kind of material that vital to metabolism. Glucose also joins in organisms' respiration process. Our research may generate a profound effect on organic chemistry because glucose is one of the most important organic compounds, and the prediction and description of glucose may reveal the truth that glucose is worth for people to do some research.
