e., a purple hue. An FRS antioxidant, by way of example, reacts to DPPH to form DPPHH, that has a lessen absorbance than DPPH because of the reduced number of hydrogen. It's radical in comparison to the DPPH-H form, mainly because it will cause decolorization, or even a yellow hue, as the number of electrons absorbed increases.
