Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of carbohydrate structure and composition.
Step 2: Detailed Explanation:
Inulin is a fructan (a polymer of fructose).
It is composed of fructose units linked by \(\beta(2 \rightarrow 1)\) glycosidic bonds.
It is a storage carbohydrate in many plants (e.g., chicory, Jerusalem artichoke).
It is a prebiotic fiber with nutritional significance.
Mannose (B), Idose (C), and combinations of mannose and idose (D) are not components of inulin.
Thus, inulin is formed from fructose.
Step 3: Final Answer:
Thus, inulin is formed from fructose, which corresponds to option (A).

- Which of the following molecules can be classified under glycosphingolipid category?
- The bicarbonate buffer is a principal buffering system in blood plasma. The ratio of the bicarbonate to carbonic acid required to maintain pH of plasma at 7.4 is:
- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?
