Explain glucose. What is the role of glucose (cane sugar) from Sucrose.

Text Solution

Verified by Experts

Glucose occurs in nature in free as well as in the combined form. It is present in sweet fruits and honey. In the combined form glucose occurs in abundance in cane sugar and polysaccharides such as starch and cellulose.
When sucrose is boiled with dilute HCl or `H_(2)SO_(4)` in alcoholic solution, glucose and fructose are obtained in equal amounts.
