Biochemical characterization of a novel ulvan lyase from Pseudoalteromonas sp. strain PLSV

, 2018
Ulvans, complex polysaccharides found in the ulvales (green seaweed) cell wall, contain predominantly 3-sulfated rhamnose (Rha3S) linked to either d-glucuronic acid, l-iduronic acid or d-xylose.

Ulvan-Na, an Ulvan Subjected to Na+ Cation Exchange, Improves Intestinal Barrier Function in Age-Related Leaky Gut

Marine Drugs
The global increase in life expectancy underscores the need to promote healthy aging, particularly by addressing age-related leaky gut syndrome, which contributes to systemic inflammation and chronic disease. This study focused on the sustainable production and functional development of Ulva meridionalis, a fast-growing seaweed, to improve gut health ...

Effects of extraction procedures and plasticizer concentration on the optical, thermal, structural and antioxidant properties of novel ulvan films

, 2019
peer reviewedActive films were produced with sulphated polysaccharides “ulvan”, extracted from the green seaweed Ulvalactuca with different extraction procedures, by varying the glycerol or sorbitol plasticizer concentration at 1% and 2% (w/v).

Ulvan from Ulva ohnoi macroalgae : Green extraction method and physicochemical characterization of the ulvan

Abstract Ulvan belongs to the class of sulfated heteropolysaccharide and is the main component of the seaweed Ulva ohnoi (U. ohnoi). Ulvan has a chemical structure similar to fucoidan, chondroitin sulfate, and hyaluronic acid, which are commonly used to develop drug delivery systems.
