Figure 7.

In vitro ACE inhibitory activity of peptides (b) compared to the positive control captopril (a). Dose-response curves were calculated using enzymatic activity values from the kinetic assay by reading fluorescence intensity (excitation 320 nm/emission 405 nm) every minute for 5 min for each dose. Results are expressed as values ± standard deviation; n = 2. Superscript letters represent statistical differences among samples. Statistical difference was determined by Tukey’s test (p < 0.05).
