Question:
Which one of the following is a tetrose sugar?
Which one of the following is a tetrose sugar?
Show Hint
Carbon count trick: Erythrose = 4 carbons = tetrose.
Updated On: Mar 28, 2026
- Ribose
- Glyceraldehyde
- Glucose
- Erythrose
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding classification of sugars.
Sugars are classified based on the number of carbon atoms they contain, such as trioses (3C), tetroses (4C), pentoses (5C), and hexoses (6C).
Step 2: Identifying tetrose sugar.
Erythrose contains four carbon atoms and hence belongs to the tetrose category.
Step 3: Analysis of options.
(A) Ribose: Pentose sugar (5 carbons).
(B) Glyceraldehyde: Triose sugar (3 carbons).
(C) Glucose: Hexose sugar (6 carbons).
(D) Erythrose: Correct — a tetrose sugar.
Step 4: Conclusion.
The tetrose sugar among the options is erythrose.
