Abstract

Polysaccharides derived from various natural sources have long been investigated and employed in a variety of industries, including food, feed, and biological activities as antioxidants, antivirals, anti-inflammatory, antimicrobial, anticancer and anticoagulants. In recent decades, micro and macroalgae have been used as sources of different active ingredients, especially because of their biocompatibility, biodegradability, non-toxicity, and specialized medicinal properties. Polysaccharides have sparked considerable interest in their use, particularly bioactive polysaccharides. The main purpose of this article was to review macro and microalgae as main sources, native biological activities, isolation, characterization, and the structural features of bioactive polysaccharides. Moreover, the review has also been focused on the chemical and functions of polysaccharide derivatives from different algal groups.
