Sucrose undergoes hydrolysis to yield an equimolar mixture of D-(+)-glucose and D-(-) fructose. The glycosidic linkage is between C₁ of a-D-glucose and C₂ of b-D-fructose, involving the reducing groups and making sucrose a non-reducing sugar.
How is sucrose hydrolyzed, and what are the monosaccharides obtained from its hydrolysis?

Sucrose hydrolysis involves breaking the glycosidic linkage between its constituent monosaccharides, glucose, and fructose. Enzymes like sucrase facilitate this process. During hydrolysis, water molecules are added, causing the glycosidic bond to cleave. The result is the formation of individual monosaccharides. Specifically, sucrose hydrolysis yields one molecule of glucose and one molecule of fructose. This process is essential for the digestion and absorption of sucrose in the human body. The separate glucose and fructose molecules can then enter metabolic pathways, providing a readily available energy source for various physiological functions.
