What is the difference between fructose and glucose?

Currently, both glucose and fructose are common in production. They are very similar, but there are still many differences.
Glucose is a monosaccharide found in many fruits, berries, juices, fruit drinks. Especially a lot of it is found in grapes, raisins, natural grape juice.
Glucose, as a monosaccharide, is part of the disaccharide – sucrose, which is also found in fruits, berries, mainly beets and cane.
Fructose, like glucose, is also a monosaccharide. It is found both in pure form and in sucrose.
Glucose is less sweet. In industry it is obtained by hydrolysis of cellulose and starch.
Fructose – due to the hydrolysis of sucrose obtained from starch hydrolysis products.
