WebMay 18, 2005 · ORAC represent a hydrogen atom transfer (HAT) reaction mechanism, which is most relevant to human biology. The Folin-Ciocalteu method is an electron transfer (ET) based assay and gives reducing capacity, which has normally been expressed as phenolic contents. The TEAC assay represents a second ET-based method. WebLowry determined that the Folin phenol reagent (phosphomolybdic-phosphotungstic acid) would bind readily to copper-treated protein. Over time, the bound reagent was reduced, resulting in a color change from yellow to blue, which could then be used to determine protein concentration. criminal intent stray cast https://mayaraguimaraes.com
