Chemistry question

I was just completing my cgp chemistry book and there is a question I don't understand
It says
"The organic compound shown on the right is leucine. which of the following statements is incorrect"
The answer is Leucine reacts with sodium hydroxide to form the salt of its conjugate acid. why is this incorrect.

i’m not entirely sure but maybe its bc when they react with a strong base like NaOH they produce a sodium carboxylate salt and water. so while a salt is produced it’s not the salt of a conjugate acid since amino acids in its zwitterion form is neutral (both acidic and basic group)

Thank you, I was thinking something similar I was also wondering if the trick is it says " conjugate acid" instead of "conjugate base"
