Quizplus · Accepted Answer

Raffinose is a trisaccharide made up of galactose, fructose, and glucose that cannot be digested by people because they lack the necessary enzyme to break the glycosidic bond holding the three sugars together. It is commonly found in beans, broccoli, and other vegetables, which can cause digestive discomfort and flatulence in some people. The other options (A) carnitine, (B) glucagon, (D) ribose, and (E) amylopectin are not related to the digestion of raffinose.
