Q: Given below are two statements: Statement I: Arginine and Tryptophan are essential amino acids. Statement II: Glycine does not have any chiral carbon.

Question Analysis & Solution

Step-by-Step Solution

  1. Statement I: Arginine and Tryptophan are essential amino acids. This statement is incorrect. While Tryptophan is an essential amino acid, Arginine is conditionally essential, meaning it's essential under certain conditions (like growth or illness) but not always.
  2. Statement II: Glycine does not have any chiral carbon. This statement is correct. Glycine's central carbon atom is bonded to two hydrogen atoms, making it achiral. A chiral carbon must be bonded to four different groups.
  3. Therefore, Statement I is incorrect, and Statement II is correct.

Correct Answer: D
