72.47, ?42.20, ?52.10, and ?67.14 kcal/mol (1 kcal=4.186 kJ), respectively. The lower IC50 value of peptide IV may be attributed to its stability when docking with ACE and changes in the flexibility and unfolding of ACE. These four bioactive peptides with ACE inhibitory ability can be ...
Fig. 7. Contribution of residues to binding energy in the docked structure of ACE2. The binding energy of CPM against ACE2 showed a high value of −79.958 ± 18.653 kJ/mol. As shown in Table 3 all the interaction energies between ACE2 and CPM showed a high value confirming profound co...
55 to 83, 87 to 103, characterized in that the mixed sulphide results from a combination of at least one element the sulphide of which has a bond energy between the metal and sulphur of less than 50.+ -.3 kcal/mol (209.+-.12 kJ/mol) and at least one element the sulphide of whic...
A pore-blocking model was found to fit the reaction rate. The reaction was essentially independent of sulfur dioxide partial pressure between 4.3 and 43 kPa and has an activation energy value of 170 kJ/mol (40.8 kcal/mol). The reduction kinetics of barium sulfate with hydrogen gas ...
Moreover, we showed that ACE inhibition activity of flavonoids compounds is directly related to their ability to bind with zinc ion in the active site of ACE enzyme. It was also revealed that OS extract contained high amount of flavonoids other than RA, TMF, SIN and EUP. As such, ...
