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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arame
, sea oak is a species of kelp, of the brown algae, best known for its use in Japanese cuisine. Description ''Eisenia bicyclis'' is indigenous to temperate Pacific Ocean waters centered near Japan, although it is deliberately cultured elsewhere, including South Korea. Arame , Food to Good Health, 2010 retrieved 8 February 2013 It grows and reproduces seasonally. Two flattened oval fronds rise from a stiff woody stipe which can be up to about tall. The fronds are shed and new ones formed annually. The plant appears both branched and feathered. It may be harvested by divers manually or mechanically, and the dried form is available year-round.

Ecklonia Stolonifera
''Ecklonia stolonifera'' (Japanese: ツルアラメ, turuarame) is a brown alga species in the genus '' Ecklonia'' found in the Sea of Japan. It is an edible species traditionally eaten in Japan. Chemistry Phlorotannins ''Ecklonia stolonifera'' contains the phlorotannins phlorofucofuroeckol A, eckol, dieckol, dioxinodehydroeckol (eckstolonol), 2-phloroeckol, phlorofucofuroeckol B, 6,6'-bieckol, triphlorethol-A, phloroglucinol and 7-phloroeckol. Those phlorotannins are responsible for the potent pharmacological effects associated with this seaweed. These molecules show a hepatoprotective activity. Oxylipins The oxylipins ecklonialactones A, B, C, D, E and F and fucosterol Fucosterol is a sterol isolated from algae such as ''Ecklonia cava'' or ''Ecklonia stolonifera ''Ecklonia stolonifera'' (Japanese: ツルアラメ, turuarame) is a brown alga species in the genus ''Ecklonia'' found in the Sea of Japan.
