Which amino acid is considered optically inactive because it lacks a chiral carbon atom?
- A.Glycine
- B.Alanine
- C.Serine
- D.Valine
Show correct answer & step-by-step solution
Correct answer: A — Glycine
Solution
- An amino acid is optically active if it has a chiral alpha-carbon.
- The structure of glycine is .
- The alpha-carbon is bonded to two identical hydrogen atoms.
- Due to the lack of four different groups, it is achiral.
- Hence the answer is (A).
