Immune-enhancing effects of anionic macromolecules extracted from Codium fragile coupled with arachidonic acid in RAW264.7 cells.

open access: yesPLoS ONE, 2020
Arachidonic acid (ARA) is an integral constituent of the biological cell membrane, conferring it with fluidity and flexibility, which are necessary for the function of all cells, especially nervous system, skeletal muscle, and immune system.

Chemical characterization and antioxidant activity of sulfated polysaccharide from the red seaweed Gracilaria birdiae [PDF]

open access: yes, 2012
Hydrocolloids from seaweeds have interesting functional properties, such as antioxidant activity and gelling ability. A polysaccharide was isolated by aqueous extraction at 90 C from the red seaweed Gracilaria birdiae (Gb), with a yield of 27.2% of the ...

19F labelled glycosaminoglycan probes for solution NMR and non-linear (CARS) microscopy [PDF]

open access: yes, 2016
Studying polysaccharide-protein interactions under physiological conditions by conventional techniques is challenging. Ideally, macromolecules could be followed by both in vitro spectroscopy experiments as well as in tissues using microscopy, to enable a

Comparative study of sulfated polysaccharides from Caulerpa spp. (Chlorophyceae). Biotechnological tool for species identification? - doi: 10.4025/actascibiolsci.v34i4.8976

open access: yesActa Scientiarum: Biological Sciences, 2012
Studies on macromolecules isolated from marine algae suggested sulfated polysaccharides (SPs) as possible molecular markers for species. We evaluated isolated and fractionated SPs from the green marine algae Caulerpa cupressoides, C.

Autotrophic and Heterotrophic Growth Conditions Modify Biomolecole Production in the Microalga Galdieria sulphuraria (Cyanidiophyceae, Rhodophyta) [PDF]

open access: yes, 2020
Algae have multiple similarities with fungi, with both belonging to the Thallophyte, a polyphyletic group of non-mobile organisms grouped together on the basis of similar characteristics, but not sharing a common ancestor.

Sulfation-dependent recognition of high endothelial venules (HEV)-ligands by L-selectin and MECA 79, and adhesion-blocking monoclonal antibody. [PDF]

open access: yes, 1994
L-selectin is a lectin-like receptor that mediates the attachment of lymphocytes to high endothelial venules (HEV) of lymph nodes during the process of lymphocyte recirculation.

A spoonful of sugar: the application of glycopolymers in therapeutics [PDF]

open access: yes, 2011
Glycopolymers, synthetic polymers displaying carbohydrate moieties, have been linked to many potential applications at the biology–chemistry interface. One area that holds particular promise is the employment of glycopolymers as vehicles for therapeutics
