Answer 1

gamma glutamyl
amino acids
H2O2

Question 2

Substrate of Szasz method of GGT determination

Answer 2

L-y-glutamyl-p-nitroanilide

Question 3

The indicator reaction p-nitroanilide or 5-amino-2-nitrobenzoate is present in which GGT determination method?

Answer 3

Szasz method

Question 4

In the Szasz method of GGT determination, L-y-glutamyl-3-carboxy-4-nitroanilide is reacted with ___ to form the end product of the reaction

Answer 4

glycylglycine

Question 5
