The Sea as a Rich Source of Structurally Unique Glycosaminoglycans and Mimetics
Microorganisms, 2017 Glycosaminoglycans (GAGs) are sulfated glycans capable of regulating various biological and medical functions. Heparin, heparan sulfate, chondroitin sulfate, dermatan sulfate, keratan sulfate and hyaluronan are the principal classes of GAGs found in ...

Fucanomics and Galactanomics: Marine Distribution, Medicinal Impact, Conceptions, and Challenges
Marine Drugs, 2012 Glycomics turned out to be a very extensive project where its subdivision is consequently emerging. This is seen by the growing number of terminologies used to define subprojects concerning particular classes of bioactive carbohydrates.

Isolation of Sulfated Galactan from Codium fragile and Its Antiviral Effect
Biological and Pharmaceutical Bulletin, 2009 A sulfated galactan (FG) was isolated from the green alga, Codium fragile. Chemical analysis revealed that FG mainly consisted of D-galactose with pyruvic acid (12.3%) and sulfate (11.0%). Methylation and NMR analyses showed that FG was composed of -->3)-beta-D-Galp-(1-->, beta-D-Galp-(1--> and -->3,6)-beta-D-Galp-(1--> residue.
