Web4 nov. 2024 · The FRAP test is based on the reduction of ferric ion (Fe 3+ →Fe 2+) under acidic conditions. The CUPRAC assay is analogous to the FRAP method and consists of the reduction of Cu 2+ to Cu 1+. The ferric (FRAP) and cupric (CUPRAC) ions’ reducing capacity was calculated according to the Formula (1): ΔA = A AR − A 0. long term effects from prilosec
