Activity

Antioxidative activity
The corn hydrolysate showed potent antioxidative activity and the peptide LDYE was isolated from the highest active fraction, so the peptide was a potentail antioxidative peptide ( The antioxidative activity of pure peptide was not determined ).
Literature report: N.D Prediction: ToxinPred
Antioxidant

Assay & Model

Enzymatic hydrolysis
Hydrolyzed with Alcalase at pH 8.0, 50℃.
