Carboxy groups probably are not significant elements in chelation for the biuret reaction; copper in the biuret reaction is stabilized by chelation with carboxyl groups of tartrate, and the absorbance of the reagent with no added biuret-reactive components probably reflects copper interacting with carboxyl groups.
