Answer
It takes longer time for fructose to be absorbed un human body's small intestine as compared to other monosaccharides.
Explanation
A human body takes fructose in the form sucrose present in fruits or vegetable, it break up into glucose and fructose with the heip of sucrase enzyme.
Absorption in small intestine
Fructose is absorbed in samll intestine join blood stream, travel along other nutrients towards liver for further metabolism ans processing.
Metabolism in liver
Once it reach to liver here and enzyme known as aldolase beta help in the metabolism of fructose. the last products of metabolized fructose are now same other monosaccharides and enter to glycolysis either through aerobic or anaerobic respiration.
In case of glucose
Glucose absorption and metabolism is not much difficult as compared to fructose, because it is directly absorbed in blood stream from small intestine and reach to those cells where it it needed for respiration (energy production).
