Functional changes of human serum albumin (HSA) induced by oral branched-chain amino acid (BCAA) supplementation. a 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging ability of purified HSA. b Antioxidant potential of plasma—biological antioxidant potential (BAP) test. c Levels of oxidative stress metabolites in plasma—derivative of reactive oxygen metabolites (d-ROMs) test. d Unbound fraction of ketoprofen to purified HSA. Values are expressed as the mean ± standard deviation. Data were analyzed by analysis of variance (ANOVA). P < 0.05 was considered to indicate a statistically significant difference. *P < 0.05, ANOVA. 3 M 3 months of treatment, 5 M 5 months of treatment, pre pretreatment, U.CARR Carratelli units
