Question

Describe the process of sucrose adsorption in human intestine.

Answer 1

As separate monosaccharides, or one-molecule sugars, glucose and fructose are free for absorption. Both sugars cross the intestinal lining through distinct complex transporters into the bloodstream of the hepatic portal system. This special system of veins is one of only three in the entire body that does not return blood directly to the heart. Instead, this system carries its blood that contains all absorbed nutrients to the liver for further processing.

Answer 2

Sucrose digestion does not begin until the sugar reaches the small intestine. our body cannot absorb polysaccharides as is, so it must first break sucrose down into its component parts. Through a process called hydrolysis, water assists in severing the glycosidic bond to separate the glucose and fructose molecules; one molecule of water is needed for each molecule of sucrose. However, this reaction naturally occurs very slowly. The presence of sucrase, an enzyme in the small intestine, accelerates this reaction.
