When sucrose is hydrolyzed, Choose... will be created as the glycosidic linkage is broken. Hydrolyzed sucrose Choose... give a p
Flauer [41]

When sucrose is hydrolyzed, <u>two reducing groups</u> will be created as the glycosidic linkage is broken. Hydrolyzed sucrose <u>will</u> give a positive Benedict's test. Hydrolysis can be achieved by adding <u>strong acids or enzymes.</u>

<h3>How is sucrose hydrolyzed in the body?</h3>

The reaction that breaks bonds and releases energy is called hydrolysis. It is a significant biological process that causes energy to be released from within our bodies. The human small intestine contains the -glucosidase enzyme sucrase, which hydrolyzes sucrose into its component monosaccharides fructose and glucose. In the brush boundary of the upper gastrointestinal system, roughly 10–25% of the fructose is converted to glucose.
