Structural characterization of ulvan extracted from Ulva clathrata assisted by an ulvan lyase

Carbohydrate Polymers, 2020
Rhamnan-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

Nutraceutical potentials of algal ulvan for healthy aging

International Journal of Biological Macromolecules, 2022
Several theories for aging are constantly put forth to explain the underlying mechanisms. Oxidative stress, DNA dysfunction, inflammation, and mitochondrial dysfunction, along with the release of cytochrome c are some of these theories. Diseases such as type 2 diabetes mellitus, intestinal dysfunction, cardiovascular diseases, hepatic injury, and even ...

Biochemical characterization of a new ulvan lyase and its applicability in utilization of ulvan and preparation of ulva oligosaccharides

Glycobiology, 2023
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.

Processing ulvan into 2D structures: Cross-linked ulvan membranes as new biomaterials for drug delivery applications

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.

Are all ulvans equal? A comparative assessment of the chemical and gelling properties of ulvan from blade and filamentous Ulva

Carbohydrate Polymers, 2021
Green seaweeds of the genus Ulva are rich in the bioactive sulfated polysaccharide ulvan. Herein we characterise ulvan from Ulva species collected from the Bay of Plenty, Aotearoa New Zealand. Using standardised procedures, we quantified, characterised, and compared ulvans from blade (U. australis, U. rigida, U. sp. B, and Ulva sp.) and filamentous (U.

NMR analysis of the chemical structure of ulvan and of ulvan-boron complex formation

Carbohydrate Polymers, 1998
The 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 ...

Ultrastructure of ulvan: A polysaccharide from green seaweeds

Biopolymers, 2009
AbstractUltrastructural analysis of the gel forming green seaweed sulfated polysaccharide ulvan revealed a spherical‐based morphology (10–18 nm diameter) more or less aggregated in aqueous solution. At pH 13 in TBAOH (tetrabutyl ammonium hydroxyde) or NaOH, ulvan formed an open gel‐like structure or a continuous film by fusion or coalescence of bead ...
