3. Results 3.1. Analytical Results TAC, uric acid, total bilirubin, thiol groups (HSA-SH), retinol, γ-tocopherol, α-tocopherol, lycopene, β-carotene, and L-ascorbic acid were quantified, as described before, in the two categories of individuals: (1) blood donors (healthy individuals), ...
capacity of serum, and the resulting absorbance at 450 nm was recorded either directly (e.g., for ascorbic acid, α-tocopherol, and glutathione) or after incubation at 500C for 20 min (e.g., for uric acid, bilirubin and albumin), quantitation being made by means of a calibration curve...
