Identification, functional gastrointestinal stability and molecular docking studies of lentil peptides with dual antioxidant and angiotensin I converting enzyme inhibitory activities
Lentil peptides showing potential antihypertensive activity were identified. Bioactive fragments derived from lentil vicilin, convicilin and legumin. Gastrointestinal digestion of peptides improved markedly their bioactivity. C-terminal heptapeptide was crucial for antioxidant and ACE inhibitory activities. ACE inhibition relies on hydrogen bonds involving residues of the catalytic site.
