Among the following statements, the one that correctly describes the products of acid-catalyzed or enzymatic hydrolysis of sucrose is

A. Only glucose, as fructose is destroyed
B. An equimolar mixture of glucose and fructose
✓
C. Glucose and galactose in a 2:1 ratio
D. Only fructose, as glucose is further broken down

📝 Explanation

Sucrose is a disaccharide of glucose and fructose. Hydrolysis of the glycosidic bond (e.g., by sucrase/invertase) yields one molecule of D-glucose and one molecule of D-fructose. This 1:1 mixture is known as invert sugar.
