Comparative Study of Sulfated Polysaccharides From Ulva Lactuca Grown in Tunisia and Morocco: in Vitro Antioxidant Activity and in Vivo Anti-Inflammatory and Anti-Ulcer Effects. [PDF]

Chem Biodivers
ABSTRACT This study presents a comparative analysis of sulfated polysaccharides extracted from Ulva lactuca collected in Tunisia (PSUT) and Morocco (PSUM). FTIR confirmed the presence of sulfate groups, while GC‐MS identified diverse sugar components. Both polysaccharides showed strong antioxidant activity, with DPPH and ABTS radical scavenging rates ...

Sulfated galactans ameliorate the cellular senescence in dermal fibroblast cells

Journal of Agriculture and Food Research
Replicative senescence of dermal fibroblast is the primary mechanism of intrinsic skin aging. Recent research has focused on the different properties of sulfated galactans (SG) derived from the red seaweed Gracilaria fisheri.

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

Is the antithrombotic effect of sulfated galactans independent of serpin? [PDF]

Journal of Thrombosis and Haemostasis, 2014
Sulfated galactans are polysaccharides with heterogeneous structures that frequently show anticoagulant activity. Their anticoagulant mechanisms are complex and distinct from those observed for heparin. Sulfated galactans act through a combination of effects involving serpin-dependent and serpin-independent mechanisms. Interestingly, these polymers can

Structural Diversity in Galactans From Red Seaweeds and Its Influence on Rheological Properties

Frontiers in Plant Science, 2020
Galactans are important components of many plant cell walls. Besides, they are the major polysaccharides in extracellular matrixes from different seaweeds, and other marine organisms, which have an acidic character due to the presence of sulfate groups ...
