WebFirst, the free radical scavenging activity of ACCE and its active ingredients, L-anserine and L-carnosine, was determined using a 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The standard antioxidant, ascorbic acid, was used as the positive control. WebThe pKa of a buffer is commonly perceived as the pH of the said buffer when the concentrations of the two buffering species are equal, and where the maximum buffering capacity is achieved. However, it is often forgotten, that when defined as above, pKa depends on buffer concentration and temperature.
