Methylation-GC-MS/FID-Based Glycosidic Linkage Analysis of Unfractionated Polysaccharides in Red Seaweeds [PDF]

Marine Drugs
Glycosidic linkage analysis was conducted on the unfractionated polysaccharides in alcohol-insoluble residues (AIRs) prepared from six red seaweeds (Gracilariopsis sp., Prionitis sp., Mastocarpus papillatus, Callophyllis sp., Mazzaella splendens, and ...

Aspen Tension Wood Fibers Contain β-(1→4)-Galactans and Acidic Arabinogalactans Retained by Cellulose Microfibrils in Gelatinous Walls [PDF]

Plant Physiology, 2013
Contractile cell walls are found in various plant organs and tissues such as tendrils, contractile roots, and tension wood. The tension-generating mechanism is not known but is thought to involve special cell wall architecture.

Tracheid cell-wall structures and locations of (1 → 4)-β--galactans and (1 → 3)-β--glucans in compression woods of radiata pine ( D. Don) [PDF]

BMC Plant Biology, 2016
Compression wood (CW) forms on the underside of tilted stems of coniferous gymnosperms and opposite wood (OW) on the upperside. The tracheid walls of these wood types differ structurally and chemically.

Galactans: an overview of their most important sourcing and applications as natural polysaccharides

Brazilian Archives of Biology and Technology, 2011
Since last decades, lot of biological and rheological properties of polysaccharides and oligosaccharides were described. Among them, galactans and more especially sulfated galactans from seaweeds have shown interesting and specific properties not only as

Sulfated Polysaccharides from Seaweeds: A Promising Strategy for Combatting Viral Diseases—A Review [PDF]

Marine Drugs, 2023
The limited availability of treatments for many infectious diseases highlights the need for new treatments, particularly for viral infections. Natural compounds from seaweed are attracting increasing attention for the treatment of various viral diseases,

Structure and Anticoagulant Activity of Sulfated Galactans [PDF]

Journal of Biological Chemistry, 2000
We have characterized the structure of a sulfatedd-galactan from the red algae Botryocladia occidentalis. The following repeating structure (-4-α-d-Galp-1→3-β-d-Galp-1→) was found for this polysaccharide, but with a variable sulfation pattern.

Anti-Thrombin, Anti-Adhesive, Anti-Migratory, and Anti-Proliferative Activities of Sulfated Galactans from the Tropical Green Seaweed, Udotea flabellum

Marine Drugs, 2018
In this study, sulfated polysaccharide-rich extracts were isolated from 22 tropical seaweeds (4 red, 11 brown, and 7 green) found in northeastern Brazil, and evaluated for the role of anticoagulant agents.

Repeated (Weekly) Intra-Articular Injections of Sulfated Galactans Attenuate Cartilage Degeneration in a Rat Model of Osteoarthritis. [PDF]

J Orthop Res
Knee osteoarthritis (OA) is characterized by progressive cartilage degeneration and remains a major cause of joint dysfunction with limited disease‐modifying therapies. This study evaluated the therapeutic potential of sulfated galactans (SG) extracted from Gracilaria fisheri in a rat OA model induced by anterior cruciate ligament transection and ...

The cell walls of different Chara species are characterized by branched galactans rich in 3-O-methylgalactose and absence of AGPs.

Physiologia Plantarum : An International Journal for Plant Biology, 2023
Streptophyte algae are the closest relatives to land plants; their latest common ancestor performed the most drastic adaptation in plant evolution around 500 million years ago: the conquest of land.

Jasmonates disrupt carrageenan synthesis during carposporogenesis in the red seaweed Grateloupia imbricata

Frontiers in Marine Science, 2023
In this study, we monitored changes in cell wall sulfated galactans in the red seaweed Grateloupia imbricata after the rapid (48 h) induction of cystocarp maturation and carpospore development by the volatile hormone methyl jasmonate (MEJA). Synthesis of
