Bioactive peptides of marine origin

The potential of peptides produced from natural sources has caught the researcher's attention over the past year. Marine peptides have physiological, "hormone-like", associated with nutritional values and other beneficial properties for human health, such as antioxidant and anti-inflammatory effects. Dietary intake of marine-origin peptides could decrease the risk of oxidative stress-related diseases such as cardiovascular, cancer, arthritis, diabetes, and Alzheimer's disease. Marin-origin peptides' advantages are low cost, environmental protection, sustainability, emulsifying, functional, solubility, foaming properties, and fewer side effects than synthetic drugs. Therefore, they have potential industrial applications. The main stages of algae bioactive peptides isolation are algae homogenization, extraction, purification by liquid chromatography, and characterization by spectroscopic methods. This presentation discusses the functional properties of peptides isolated from algae, their application in food, nutricosmetic, and pharmaceutical industries, and the isolation and characterization strategies to obtain them
