Antioxidant Effects of Sheep Whey Protein on Endothelial Cells

Figure 4

Effects of whey protein on (a) TBARS levels and (b) protein carbonyl levels as evaluated by spectrophotometer presented as % of control. Cells were studied under three conditions: under normal conditions (control), under treatment with tBHP (0.3 mM) for 1 h, and under the combination of whey protein (0.78–6.24 mg of protein mL⁻¹) for 24 h and tBHP (0.3 mM) for 1 h. All values are presented as the mean ± SEM of 3 experiments (). Statistically significant compared to tBHP alone (). ^#Statistically significant compared to control (). ^¥Statistically significant compared to 0.78 mg of protein mL⁻¹ (). ^§Statistically significant compared to 1.56 mg of protein mL⁻¹ ().
