Sulfated polysaccharides from marine diatoms: Insight into molecular characteristics and biological activity

Abstract

<abstract> <p>Marine algae are a valuable source of sulfated polysaccharides presenting varied structural characteristics and biological activities. Regarding sulfated polysaccharides extracted from marine microalgae, molecular characteristics and bioactivity have yet to be fully explored, especially in diatoms. Sulfated polysaccharides from marine diatoms have great potential to produce numerous health benefits and lead to new biomedical materials. Nevertheless, these potential applications are based on the polysaccharide molecular characteristics, which define their functional properties. Therefore, a detailed understanding of sulfated polysaccharides from marine diatoms may represent the starting point for a broad development of innovative applications, especially in the biomedical area. In this context, the present manuscript aims to review marine diatom sulfated polysaccharides' molecular characteristics and biological activity, looking for a more profound knowledge of these macromolecules and their potential applications.</p> </abstract>
