LR5

The IC50 values for the O2-· scavenging ability of the original and replacement rice peptides are shown in Figure 1A. Compared with the original pentapeptide LR5, the IC50 values of the replacement pentapeptides AR5 and LAR5 with reduced hydrophobicity increased from 2.6561 ± 0.0031 mmol/L to 6.985 ± 0.0002 mmol/L (p < 0.01) and 3.633 ± 0.0071 mmol/L (p < 0.01), respectively.

Compared with the original pentapeptide LR5, the IC50 values of the replacement pentapeptides AR5 and LAR5 increased from 0.6476 ± 0.0032 mmol/L to 0.6702 ± 0.0019 mmol/L (p < 0.05) and 0.6561 ± 0.0025 mmol/L (p < 0.05), respectively.
