Question:
Identify acidic amino acid from following list represented by three letter symbols.
Identify acidic amino acid from following list represented by three letter symbols.
Show Hint
Aspartic acid (Asp) and Glutamic acid (Glu) are the two standard acidic amino acids.
Updated On: Apr 30, 2026
- Thr
- Trp
- His
- Glu
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Acidic amino acids contain two carboxyl groups and one amino group.
Step 2: Analysis
- Thr (Threonine): Neutral (contains -OH). - Trp (Tryptophan): Neutral (aromatic). - His (Histidine): Basic (imidazole ring). - Glu (Glutamic Acid): Acidic (contains an additional -COOH group).
Step 3: Conclusion
Glu is the acidic amino acid.
Final Answer:(D)
