Which from following pairs of carbohydrates produce equal quantity of glucose on hydrolysis per mole?
Options
- ASucrose and Lactose
- BLactose and Maltose
- CSucrose and Maltose
- DRaffinose and Maltose
Correct answer
A. Sucrose and Lactose
Step-by-step solution
Hydrolysis of carbohydrates releases constituent monosaccharides, with glucose yield depending on molecular structure. Sucrose hydrolyzes to glucose and fructose: Sucrose + H 2 O Glucose + Fructose, yielding 1 mole glucose per mole sucrose. Lactose hydrolyzes to galactose and glucose: Lactose + H 2 O Galactose + Glucose, yielding 1 mole glucose per mole lactose. Maltose , composed of two glucose units, hydrolyzes to two glucose molecules: Maltose + H 2 O 2 Glucose, yielding 2 moles glucose per mole maltose. Raffino
