Question:
Formula of Glycine is:
Formula of Glycine is:
Show Hint
Always remember amino acid general formula: NH$_2$-CHR-COOH; glycine has R = H.
Updated On: Jun 20, 2026
- C$_3$H$_7$O$_2$N
- C$_3$H$_7$O$_3$N
- C$_{16}$H$_{32}$O$_2$
- C$_2$H$_5$O$_2$N
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding glycine structure.
Glycine is the simplest amino acid with the molecular structure NH$_2$-CH$_2$-COOH.
Step 2: Counting atoms systematically.
From NH$_2$-CH$_2$-COOH:
Carbon (C) = 2
Hydrogen (H) = 5
Oxygen (O) = 2
Nitrogen (N) = 1
Step 3: Writing molecular formula.
Thus, the molecular formula becomes C$_2$H$_5$O$_2$N.
Step 4: Comparing with options.
Only option (4) matches the correct atomic composition.
Step 5: Final verification.
The standard known formula of glycine confirms the derived result.
Step 6: Final conclusion.
Therefore, correct answer is: \[ \boxed{\text{C}_2\text{H}_5\text{O}_2\text{N}} \]
