The sugars in fruits are various monosaccharides and disaccharides, among which glucose, fructose and sucrose are the most common.
Glucose and fructose are the most basic monosaccharides, and their content in fruits is very high. Glucose is a six carbon sugar with molecular formula of C6H12O6. It is an important substance for energy metabolism in human body. Fructose is also a six carbon sugar with the molecular formula of C6H12O6. Its metabolism speed in human body is slower than glucose, but its sweetness is higher than glucose.
Sucrose is a disaccharide composed of glucose and fructose, which is one of the main sugars in fruits. The molecular formula of sucrose is C12H22O11. Its sweetness is higher than that of monosaccharide, but its metabolic rate is slower than that of monosaccharide.
In addition to the above three sugars, fruits also contain other polysaccharides, alcohols and proteins. These ingredients play an important role in human health.
