Plant sources of bioactive peptides

Plant proteins constitute as one of the major sources of food proteins for the human body. In addition, they provide biological functions such as antioxidant and immunomodulation associated with naturally occurring and process-derived peptides that can alter signaling pathways promoting overall health. This chapter provides an overview on some of the plant sources of bioactive peptides. In addition, the procedures employed in the isolation, production, and purification of these bioactive peptides are discussed. Throughout the chapter, examples of plant-derived bioactive peptides and their bioactive properties are given. Discussion on the mechanistic insights as well as opportunities and challenges in the use of plant-derived peptides in human health studies are presented. Future studies answering these opportunities and challenges are needed to move forward the utilization of plant-derived peptides for the promotion of human health.
