Analysis of Iron and Polyphenols in Brown and Red Macroalgae from Antarctica
Antarctica, the White Continent, is the refuge of typical species, where temperatures range from -85 to2 oC, UV radiation can penetrate 30 m depth and salinity reaches 32-34%. Among these species, brownmacroalgae (Pheophytas) and red macroalgae (Rhodophytas) are mainly evaluated as potential food an...
