Development of edible films and coatings from alginates and carrageenans.
TL;DR: This review highlights production and characteristics of carrageenan and alginate as sources of film-forming materials and indicates that water-soluble hydrocolloids like polysaccharides usually impart better mechanical properties to edible films and coatings than do hydrophobic substances.

Potential antioxidant capacity of sulfated polysaccharides from the edible marine brown seaweed Fucus vesiculosus.
TL;DR: This fraction showed the highest potential to be antioxidant by the ferric reducing antioxidant power (FRAP) assay, followed by the alkali- and water-soluble fractions, and potentially could be used as natural antioxidants by the food industry.

Studies on the Sequence of Uronic Acid Residues in Alginic Acid.
Journal ArticleDOI
Uronic acid sequence in alginate from different sources
TL;DR: Alginate may be considered as a block co-polymer of D -mannuronic and L -guluronic acids, and consists of three types of blocks: homopolymeric blocks of mannuronic acid and of guluronic Acid, and blocks with an alternating sequence (MG).

Vibrational spectra of carbohydrates.
TL;DR: This chapter describes the various aspects of the vibrational spectra of carbohydrates, and the analysis of crystallographic results shows the important role played by anomeric center in the structure of sugars.

Structure and antitumour activity of fucoidan isolated from sporophyll of Korean brown seaweed Undaria pinnatifida
Andriy Synytsya,Woo Jung Kim,Sung Min Kim,Radek Pohl,Alla Synytsya,František Kvasnička,Jana Čopíková,Yong Il Park +7 more
TL;DR: The Miyeokgui fucoidan showed antitumour activity against PC-3 (prostate cancer), HeLa (cervical cancer), A549 (alveolar carcinoma), and HepG2 (hepatocellular carcinoma) cells, in a similar pattern to that of commercial fucoidy.
