Question:easy
Identify the hydrolysis product of starch.
Identify the hydrolysis product of starch.
Show Hint
Keep in mind that starch, glycogen, and cellulose are all homopolymers of glucose. Therefore, the complete hydrolysis of any of these three major polysaccharides will always yield pure glucose!
Updated On: Jun 1, 2026
- Glucose
- Fructose
- Galactose
- Ribose
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Know what starch is.
Starch is a big carbohydrate. Its long chains are made by joining many small sugar units together.
Step 2: See which sugar unit it uses.
Every unit in starch is a glucose molecule. There is no other kind of sugar hidden inside it.
Step 3: Break it down.
When water and acid (or an enzyme) cut all the links, only that one building block is set free.
$$(\text{C}_6\text{H}_{10}\text{O}_5)_n + n\text{H}_2\text{O} \rightarrow n\,\text{C}_6\text{H}_{12}\text{O}_6$$
So the only product is glucose.
\[ \boxed{\text{Glucose}} \]

- Carbohydrates are essential for life in both plants and animals. Carbohydrates are used as storage molecules as starch in plants and glycogen in animals. Chemically, they are polyhydroxy aldehydes or ketones. On the basis of their behavior on hydrolysis, carbohydrates are classified as monosaccharides, oligosaccharides, and polysaccharides.
All monosaccharides are reducing sugars, i.e., they are oxidized by Tollens' reagent and Fehling’s solution. A monosaccharide like glucose is an aldose, and its molecular formula was found to be C6H12O6. After reacting with different reagents like HI, H2N–OH, Bromine water, (CH3)2O, etc., its structure was found to contain one aldehyde group, one primary alcoholic group (–CH2OH), and four secondary alcoholic groups (>CHOH).
Despite having the aldehyde group, glucose does not give some of the reactions of aldehyde groups like Schiff’s test or NaHSO3 addition. This explains the existence of glucose in two cyclic hemiacetal forms, which differ only in the configuration of the hydroxyl group at C–1.- CBSE Class XII - 2024
