International Journal of Pharmaceutics, 2012 The polysaccharide ulvan, composed of sulphated rhamnose, glucoronic and iduronic acids was used to produce polymeric membranes by solvent casting. As ulvan is soluble in water, a cross-linking step was necessary to render the membrane insoluble in water and stable at physiological conditions.

Structural characterization of ulvan extracted from Ulva clathrata assisted by an ulvan lyase
Carbohydrate Polymers, 2020Rhamnan-rich sulfated polysaccharides extracted from green algae (ulvan) constitute potentially useful natural materials for drug development. However, the characterization of their complex structures poses a challenge for their application. In this study, the structure of ulvan extracted from Ulva clathrata was analyzed with the assistance of an ulvan

Abstract Ulva is globally distributed specie and has a high economic value. Ulvan is one of the main active substances in Ulva, which has a variety of biological properties. Ulvan lyase degrades ulvan through a β-elimination mechanism which cleaves the β-glycosidic bond between Rha3S and GlcA or IdoA.

NMR analysis of the chemical structure of ulvan and of ulvan-boron complex formation
Carbohydrate Polymers, 1998The NMR spectroscopic analysis of autohydrolysate fragments obtained from the gel-forming water-soluble cell-wall sulphated polysaccharides from the green seaweedUlva sp. allowed the identification of two major repeating units in ulvan. These were the aldobiouronic acids → 4)-β-DGlcpA-(1 → 4)-α-L-Rhap 3-sulphate and → 4)-α-L-IdopA-(l → 4)-α-L-Rhap 3 ...
