Arginine is an amino acid. The Sakaguchi Reaction functions as a qualitative test for this substance, whether on its own or in a protein.
The Sakaguchi test is a specific qualitative test for the detection of a specific type of protein with the amino acid containing the guanidinium group. In basic conditions, alpha naphthol and sodium hypobromite/chlorite react with the aforementioned compound to form red-orange complexes.
Because this test is extremely sensitive and if there will be an in order addition of reagents, the presence of Arginine will not be sufficient to produce the desired outcome.
The Sakaguchi reagent consists of 1-Naphthol and a drop of sodium hypobromite. The guanidine group of arginine in proteins reacts with the Sakaguchi reagent.
A red color is the positive result>
Arginine.
Sakaguchi test detect arginine in proteins; the 1-naphtol with a bit of sodium hypobromite react with arginine and produce a red color complex.
