Summary
Glutamine, often abbreviated as the 3-letters Gln or the 1-letter Q, is one of the 20 amino acids that make up proteins in our body. Glutamine’s R-group consists of an amide at the end of a long, 2-carbon chain. This amide group makes glutamine a polar, hydrophilic amino acid that dissolves easily in water. Finally, glutamine is neutral or uncharged at physiological pH.
Key Points
- Glutamine
- Abbreviations
- Gln, Q
- Chemical Structure
- R group: -CH2-CH2-Amide
- Amide
- Contrast vs. Glutamate (which has carboxyl instead of amide)
- 2 bridging methylene carbons (-CH2-CH2-)
- Contrast vs. Asparagine (which has only 1 bridging carbon)
- Amide
- Polarity
- Polar (water soluble/hydrophilic)
- Charge at pH 7
- Neutral (0)
