Abstract
Seaweed, a promising source of nutritional proteins, including protein hydrolysates, bioactive peptides, phycobiliproteins, and lectins with multi-biological activities. Seaweeds-derived proteins and peptides have attracted increasing interest for their potential applications in dietary supplements, functional foods, and pharmaceuticals industries. This work aims to comprehensively review the preparation methods and virtual screening strategies for seaweed-derived functional peptides. Additionally, it elucidates their diverse biological activities, mechanisms of action, and industrial applications. Enzymatic hydrolysis appears as the most effective method for preparing functional peptides from seaweeds. Computational virtual screening has also proven to be a valuable strategy for assessing the nature of the peptides. Seaweeds-derived proteins and peptides offer numerous health benefits, including alleviation of oxidative stress, anti-diabetic, anti-hypertensive, anti-inflammatory, anti-obesity, anti-cancer, and anti-microbial activities. Studies indicate that proteins hydrolysates and peptides derived from seaweeds with low molecular weight and aromatic and/or hydrophobic amino acids are particularly significant in contributing to these diverse bio-activities. Furthermore, seaweeds-derived proteins and peptides hold great promise for industrial applications owing to the broad spectrum of bio-functional effects. They can be used as active ingredients in food products or pharmaceuticals for disease prevention and treatment, and as food preservatives, potentially with fewer side effects.
