Gallic Acid Functionalization Improves the Pharmacological Profile of Fucoidan B: A Polysaccharide with Antioxidant Properties

Polysaccharides
Fucoidan B (FucB) is a sulfated polysaccharide with recognized biological activity. In this study, FucB was chemically modified through redox conjugation with gallic acid (GA) to obtain FucB-GA, aiming to enhance its antioxidant properties.

Structural Analysis and Anticoagulant Activities of the Novel Sulfated Fucan Possessing a Regular Well-Defined Repeating Unit from Sea Cucumber

Marine Drugs, 2015
Sulfated fucans, the complex polysaccharides, exhibit various biological activities. Herein, we purified two fucans from the sea cucumbers Holothuria edulis and Ludwigothurea grisea. Their structures were verified by means of HPGPC, FT-IR, GC–MS and NMR.

Algal glycans promote microbial turnover of organic matter through stabilization of subtidal permeable sandy sediments

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Permeable sands on continental shelves host microbial communities that drive organic carbon turnover, oxygen fluxes and nitrogen loss. Advective porewater flow associated with sedimentary bedforms maintains these rates and fluxes. Modeling and laboratory studies suggest that advective porewater flow is tightly coupled to bedform stability ...

Recent Progressions in Applications of Bioactive Polysaccharides in Food and Health Sciences: A Comprehensive Review

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
Polysaccharides play a pivotal role in the development of safe and healthy foods. They ameliorate fatigue, preserve the microflora of the gastrointestinal tract, and provide health for the gut in living organisms. These biopolymers are applied for the fabrication of breakthrough drug delivery systems and potential platforms in regenerative medicine ...

Presence of Exogenous Sulfate Is Mandatory for Tip Growth in the Brown Alga Ectocarpus subulatus

Frontiers in Plant Science, 2020
Brown algae (Phaeophyceae) are multicellular photoautrophic organisms and the largest biomass producers in coastal regions. A variety of observations indicate that their extracellular matrix (ECM) is involved with screening of salts, development, cell ...

Structure and antiviral activity of sulfated fucans from Stoechospermum marginatum

Phytochemistry, 2006
A sulfated fucan containing fraction (SmWE) was isolated from water extract of the brown seaweed Stoechospermum marginatum collected from the Arabian Sea. Anion exchange chromatography of the crude fraction results in the production of a sulfated fucan (F3) having a molecular mass of 40 kDa and specific rotation [alpha]D(30) - 124 degrees (c 0.5, H2O).
