Milk-derived bioactive peptides protect against oxidative stress in a Caco-2 cell model

or TbOOH, and, in addition, they showed a protective effect on the thiol-related antioxidant enzymes thioredoxin reductase and glutathione reductase. Finally, they caused a decrease of ROS production induced by TbOOH in Caco-2 cells. The reported results highlight the relevant antioxidant role played by bioactive peptides in cells, which adds to other previously known properties.
