	Analipus Japonicus ''Analipus japonicus'', or sea fir, is a brown alga species in the genus ''Analipus''. This species contains the phlorotannins difucol, trifucol, tetrafucol A and B, two pentafucols, four hexafucols, a heptafucol mixture and halogenated compounds such as bromo- and chlorotrifucol, 5'-bromo- and 5'-chlorotetrafucol-A as well as 5'-bromo- and 5'-chloropentafucol-A. This brown alga species is a Pacific subtropical-boreal plant species that populates the stone coast from the Sea of Japan to the Bering Sea and from Alaska to California. The ''Analipus'' thallus is an abiding lobed basal crust ("tar spot"), from which a short lived vertical axis with a number of branches develop. From the branches develop a unilocular or multilocular sporangia advance on the branches.

	Scytothamnus Australis ''Scytothamnus australis'' is a brown alga species in the genus ''Scytothamnus'' found in New Zealand. It is a sulphated polysaccharide and the type species in the genus. The species contains the phlorotannins trifucol, tetrafucol A, tetrafucol B, cis-pentafucol A, diphlorethol A and triphlorethol A. Distribution ''Scytothamnus australis'' has a southern circumpolar distribution and has been recorded to have been present from the waters of southern Australia, New Zealand and Chile. Description ''Scytothamnus australis'' is a larger, more robust species than ''Scytothamnus fasciculatus'', but possesses a similar branching pattern and broadly comparable vegetative anatomy. Cell structure As with the other species of ''Scytothamnus'', ''Scytothamnus australis'' has a stellate (star-shaped) chloroplast with a central pyrenoid and is perforated by channels of cytoplasm. Reproductive structure ''Scytothamnus australis'' has a unilocular sporangia reproductive structure which me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Phlorotannin Phlorotannins are a type of tannins found in brown algae such as kelps and rockweeds or sargassacean species, and in a lower amount also in some red algae. Contrary to hydrolysable or condensed tannins, these compounds are oligomers of phloroglucinol (polyphloroglucinols). As they are called tannins, they have the ability to precipitate proteins. It has been noticed that some phlorotannins have the ability to oxidize and form covalent bonds with some proteins. In contrast, under similar experimental conditions three types of terrestrial tannins (procyanidins, profisetinidins, and gallotannins) apparently did not form covalent complexes with proteins. These phenolic compounds are integral structural components of cell walls in brown algae, but they also seem to play many other secondary ecological roles such as protection from UV radiation and defense against grazing. Biosynthesis and localization Most of the phlorotannins' biosynthesis is still unknown, but it appears they ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
