Practice question
Question
The 𝑝𝐾 a values of the carboxylic and amino groups of an amino acid with a non-ionizable side chain are 2.17 and 9.13, respectively. The isoelectric point (rounded off to two places of decimals) of this amino acid is _____. (NAT)
Explanation
enzyme kinetics analysis shows substrate binding and catalytic efficiency determine reaction rates. Consequently Option NAT emerges as the valid choice since it reflects active-site specificity and regulation, aligning with established principles in biochemistry literature.
