Sea water and algae contain magnesium, strontium and algal polysaccharides fucoidan laminara which have antibacterial and antiviral properties.
Aldavine is a highly-potent cosmetic active ingredient derived from two different algae leading to the association of two sulphated algal polysaccharides.
The whole cycle of investigations concerning algal polysaccharides was introduced by elucidation of promising seaweed species containing a nearly neutral galactan fraction close to agarose (Fig.
INVESTIGATIONS OF THE COMPOSITION AND STRUCTURE OF ALGAL POLYSACCHARIDES
During a long period the content of micro- and trace elements in algal polysaccharides and in seaweeds has been investigated mainly by methods of neutron activation analysis.
Although some natural algal polysaccharide mixtures have been used already for centuries, their fractionation and structural investigations were started quite recently.
