Inulin, a storage polysaccharide found in the roots of Dahlias and chicory, is a polymer of:
Answer and explanation
Correct answer: B. Fructose
- Step 1: Inulin is a natural storage fructan accumulated by plants in the Asteraceae family (such as Dahlia and Jerusalem artichoke).
- Step 2: It is a linear homopolysaccharide consisting of repeating -D-fructofuranose units ending in a glucose moiety.
- Step 3: Because human enzymes cannot hydrolyze inulin and it is neither absorbed nor secreted by renal tubules, it is used clinically to measure glomerular filtration rate (GFR).
Answer
Fructose.
Why not the others: Glucose forms glycogen, starch, and cellulose; Galactose forms galactans and agar; Mannose forms mannans.
