1Top value represents correlation (r value) and bottom value in parenthesis represents significance (P-value). If no value is given, it was not found to be significant (-) at P ≤ 0.10. There were no correlations observed between SO treatment and serum TBARS, serum FRAP, urinary FRAP (ferric reducing ability of serum), liver PC, liver SOD, and liver GPx so they were removed from the table.
2PV = peroxide value; AnV = p-anisidine value; TBARS = thiobarbituric acid reactive substances; OFA = oxidized fatty acids; TPC = total polar compounds; PTAG = polymerized triacylglerides; OSI = oxygen stability index; HEX = hexanal; DDE = 2,4-decadienal; HNE = 4-hydroxynonenal; Ratio = ratio of aldehydes as described by Wang et al., 2016; TOC = total tocopherols; PC = protein carbonyls; GPx = glutathione peroxidase activity; ISP = F2-isoprostanes; 8-OH-2dG = 8-hydroxy-2’deoxyguanosine; CAT = catalase activity.
