JEE Mains · Chemistry · STD 12 - 10. Biomolecules
Identify the correct statement among the following:
- A All naturally occurring amino acids except glycine contain one chiral centre.
- B All naturally occurring amino acids are optically active.
- C Glutamic acid is the only amino acid that contains a-COOH group at the side chain.
- D Amino acid, cysteine easily undergo dimerization due to the presence of free SH group.
Answer & Solution
Correct Answer
(D) Amino acid, cysteine easily undergo dimerization due to the presence of free SH group.
Step-by-step Solution
Detailed explanation
* Isoleucine has 2 chiral centre * Glycine is optically inactive * Aspartic acid also contain COOH group at the side chain. * Cysteine easily dimmerise due to free SH group
