How to identify this amino acid? ### Amino Acid Structure IdentificationThe structure of an amino acid is shown. Identify the amino acid from the options provided.**Options:**- O proline- O histidine- O lysine- O arginine**Structure Description:**The diagram displays the molecular structure of an amino acid. Key features of the structure include:- A five-membered ring, which is characteristic of proline.- A central carbon (alpha carbon) bonded to: - An amino group \((\text{NH}_2^+)\) - A hydrogen atom - A carboxylate group \((\text{O}^-\text{C}=\text{O})\) - A three-carbon chain forming a cyclic structure (pyrrolidine ring)This configuration is unique to the amino acid proline, which distinguishes it from other amino acids due to its secondary amine group forming the ring.

Here we are required to identify the one of twenty naturally occurring amino acid.Amino acid are amphoteric biomolecules which have both the carboxylic acid COOH group and amine NH2 group. There are twenty amino acid. Different amino acid have different side group. Some amino acid have side chain which are polar ,some are non polar, some are acidic and Some are basic. From the side chain we can identify the amino acid. The amino acid prefer to exist in zwitter ionic form.The structure of the given amino acid matches with proline. Conclusion The given amino acid is proline Option a is correct.
