MCQ
Which amino acid is achiral?
- AAlanine
- BValine
- CProline
- DGlycine
✓
Answer
- Glycine
Explanation:
A chiral center of a molecule is the atom that is bonded to four different chemical species.
Glycine is the simplest amino acid. Its side-chain (called the R-group) has two hydrogen atoms.
Because it has two hydrogen atoms as its sidechain, glycine is the only achiral amino acid.
