Title: Preparation, structures, and biological functions of rhamnan sulfate from green seaweed of the genus Monostroma: A review. Author: Chi Y, Jiang Y, Wang Z, Nie X, Luo S. Journal: Int J Biol Macromol; 2023 Sep 30; 249():125964. PubMed ID: 37487994. Abstract: Rhamnan sulfate, a rhamnose-rich sulfated polysaccharide, is present in the cell walls of green seaweed belonging to the genus Monostroma. This macromolecule demonstrates promising therapeutic properties, including anti-coagulant, thrombolytic, anti-viral, anti-obesity, and anti-inflammatory activities, which hold potential applications in food and medical industries. However, rhamnan sulfate has not garnered as much attention from researchers as other seaweed polysaccharides, including alginate, carrageenan, and fucoidan. This review discusses the extraction and purification techniques of rhamnan sulfate, delves into its chemical structures and related elucidation approaches, and provides an overview of its biological functions. Future research should focus on the structure-activity relationship of rhamnan sulfate and the industrial preparation of rhamnan sulfate with a specific homogeneous structure to facilitate its practical applications.[Abstract] [Full Text] [Related] [New Search]
