Activity

Antioxidative activity
This peptide yielded antioxidative activity against the peroxidation of linoleic acid in an aqueous system at pH 7.0. The antioxidative activity was measured with 0.8 μg of P1 and the peptide concentrations ranged from 3.3 × 10^-7 to 4.5 × 10^-5 M, in which range the antioxidative activity was dose dependent and no prooxidative activity was observed (data not shown).

Assay & Model

linoleic acid peroxidation
Enzymatic hydrolysis
Peptide obtained by hydrolysis of a soybean β-conglycinin (7S protein) by use of protease S.
