Unlabelled: High molecular weight (HMW; >1 kDa) carbohydrates are a major component of dissolved organic matter (DOM) released by benthic primary producers. Despite shifts from coral to algae dominance on many reefs, little is known about the effects of exuded carbohydrates on bacterioplankton communities in reef waters. We compared the monosaccharide composition of HMW carbohydrates exuded by hard corals and brown macroalgae and investigated the response of the bacterioplankton community of an algae-dominated Caribbean reef to the respective HMW fractions.

- Fucoidans are polysaccharides from brown seaweeds that may help protect against oxidative stress, particularly ferroptosis, linked to retinal and brain diseases.
- The study evaluated various fucoidan extracts' effectiveness in reducing cell death in specific retinal and neuronal cell lines, finding limited protective effects.
- Results suggest that the antioxidant properties of fucoidans vary by cell type and extraction methods, signaling a need for further research to understand their potential health benefits and mechanisms.
