Abstract: Bioactive peptides from marine sources have a broad spectrum of biological properties, including antioxidant, anti-hypertensive and anti-atherogenic activity. The molecular mass of antioxidant peptides from marine sources is generally less than 3 kDa, and most of them are produced by pepsin hydrolysis. The molecular mass of antihypertensive peptides from marine sources, which have angiotensin converting enzyme inhibitory activity, is generally less than 1.5 kDa. Peptides extracted from chlorella can inhibit the production of endothelial cell selectin and have anti-atherosclerotic activity. Peptides derived from the hydrolysis of green-lipped mussel by neutral protease can promote the proliferation of platelet endothelial cell adhesion molecule 1, fibroblast growth factor and epidermal growth factor, and repair skin wound. Peptides derived from proteins in fish processing byproducts have good foaming and emulsifying properties; the higher the degree of hydrolysis, the better the solubility. This article aims to review the information on bioactive peptides isolated from different marine sources, with focus on different biological activities and functional properties as well as different industrial applications. It is expected to promote the development of functional products from bioactive peptides derived from marine sources and provide a theoretical reference for further studies on their biological and functional characteristics.
