Fucoidan: An Update on Function, Role in Human Health and Applications

open access: yesChemical Biology &Drug Design, Volume 107, Issue 5, May 2026.
Fucoidan is a promising bioactive compound with anti‐inflammatory, anticoagulant, anticancer, antioxidant, antiviral, and cardioprotective properties. In addition, thanks to its epigenetic potential, ability to modulate autophagic mechanisms and possibility adjuvant agent or bioactive component of the drug delivery systems, fucoidan is a promising ...

Hydrothermally Stable, Conformal, Sulfated Zirconia Monolayer Catalysts for Glucose Conversion to 5-HMF [PDF]

open access: yes, 2015
The grafting and sulfation of zirconia conformal monolayers on SBA-15 to create mesoporous catalysts of tunable solid acid/base character is reported. Conformal zirconia and sulfated zirconia (SZ) materials exhibit both Brönsted and Lewis acidity, with ...

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

open access: yesLimnology 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 ...

Females of the sea urchin Strongylocentrotus purpuratus differ in the structures of their egg jelly sulfated fucans [PDF]

open access: yesGlycobiology, 1998
The egg jelly coats of sea urchins contain sulfated fucans which bind to a sperm surface receptor glycoprotein to initiate the signal transduction events resulting in the sperm acrosome reaction. The acrosome reaction is an ion channel regulated exocytosis which is an obligatory event for sperm binding to, and fusion with, the egg. Approximately 90% of

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

open access: yesFood 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 ...

Sulfated Fucan Oligosaccharides Elicit Defense Responses in Tobacco and Local and Systemic Resistance Against Tobacco Mosaic Virus

open access: yesMolecular Plant-Microbe Interactions, 2003
Sulfated fucans are common structural components of the cell walls of marine brown algae. Using a fucan-degrading hydrolase isolated from a marine bacterium, we prepared sulfated fucan oligosaccharides made of mono- and disulfated fucose units ...

From Sea to Sweet: Seaweed's Role in Nutritious and Sustainable Confectionery

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 1, January 2026.
ABSTRACT Seaweed is increasingly recognized as a multifunctional ingredient in confectionery products, owing to its exceptional nutritional profile, functional properties, and environmental sustainability. This review highlights the integration of seaweed and seaweed‐derived compounds into a wide range of confectioneries, including chocolates, puddings,

Antiproliferative Activity of Fucan Nanogel

open access: yesMarine Drugs, 2012
Sulfated fucans comprise families of polydisperse natural polysaccharides based on sulfated l-fucose. Our aim was to investigate whether fucan nanogel induces cell-specific responses.

The optimization of crop response to climatic stress through modulation of plant stress response mechanisms. Opportunities for biostimulants and plant hormones to meet climate challenges.

open access: yesNew Phytologist, Volume 249, Issue 1, Page 130-151, January 2026.
Summary This review discusses the use of agronomic management practices to enhance crop stress resilience to climate stress through the modulation of natural plant growth regulatory pathways. The use of biostimulants or plant hormones to improve crop resilience is subject to strict regulatory oversight if changes in the regulation of plant growth are ...

Perspective on the Use of Sulfated Polysaccharides from Marine Organisms as a Source of New Antithrombotic Drugs

open access: yesMarine Drugs, 2015
Thromboembolic diseases are increasing worldwide and always require anticoagulant therapy. We still need safer and more secure antithrombotic drugs than those presently available. Sulfated polysaccharides from marine organisms may constitute a new source
