THE RED ALGAE
To survive in extreme conditions, it triggers the biosynthesis of many active compounds such as sulphated polysaccharides, pigments and polyunsaturated fatty acids which help it fight external aggressions such as light radiation, extreme pH and salinity.
Thus, its natural bioproduction of rich scarlet pigments, various nourishing vitamins, moisturizing lipids and regenerating polysaccharides offers it natural protection.
For illustration, the sulphated polysaccharides that it produces and excretes form a gelatinous envelope, protecting it from oxidation and cell damage.
