| Abstract |
Macroalgae are emerging as promising sources of bioactive compounds, renowned for their health-promoting benefits. In the last decades, the glycerol galactoside, floridoside, emerged as one of the dominant carbohydrates in red algae, in addition to occurring in dinoflagellates and cryptophytes. Given the fragmented nature of current knowledge on this compound and its potential, this review was performed to assess past and recent research, to identify knowledge gaps, and offer direction for future research. In this extensive literature review, we identified 123 relevant publications, primarily focusing on occurrence and production of this compound and its ecophysiological functions. Moreover, future research directions and emphasis of floridoside extraction and characterization as well as their functional activities and applications are highlighted and explored. Floridoside and its isomers, Dand L-isofloridoside, were found to play an important role in osmotic acclimation in red algae and are considered key photosynthetic and reserve products which can act as the carbon precursor of polysaccharides for cell wall development in Rhodophyta. Additionally, it exhibits multiple bioactive properties, including antioxidant, antimicrobial, immunomodulatory and anti-inflammatory effects, with potential therapeutic applications. This study uniquely integrates both ecological, biochemical and systematic insights to guide future research and industrial applications. |
