Brown Algae

Brown algae belong to a very large group called the Heterokontophyta.

This algae is most noted for its having chloroplasts.

The chloroplast in brown algae is surrounded by four membranes, suggesting an origin that brown algae may be the result of a symbiotic relationship between two or more cells.

 

It is the power of the chloroplasts that allows the amazing array of chemicals to be created by the plant. 

 These nutrients are contained in their cells.

Brown algae should be an ingredient in every diet.

Brown allgae are rich in dietary fiber, minerals, lipids, proteins, omega-3 fatty acids, essential amino acids, polysaccharides, and vitamins A, B, C, and E.

Low in fat and low in calories.

This makes them one of the most nutritionally-packed foods on the planet.

The bioactivity of algae includes many numerous health-promoting effects, including anti-oxidative, anti-inflammatory, antimicrobial, and anti-cancer effects due to the library of compounds found in the seaweed.

 

This universe of bioactive metabolites include brominated phenols, brominated oxygen heterocyclics, nitrogen heterocyclics, kainic acids, guanidine derivatives, phenazine derivatives, amino acids and amines, sterols sulfated polysaccharides and prostaglandins.

 

The most studied compound, fucoxanthin, is a type of xanthophyll and an accessory pigment in the chloroplasts.

Focoxanthin has preventitive potential.

 

An essential adaptive feature of algae is the ability to couple oxidative reactions resulting from exposure to sunlight and air with the halogenations of various various compounds,

 

This provides a library of halogenated compounds that promote the seaweed's survival.

 

They act as a defense against predators, or speed tissue repair, or aids in adhesion, or protects against reactive species generated by oxidative processes.

 

Marine organisms use bromine to increase the biological activity of secondary metabolites.

One order of brown algae, the Laminariales, have developed a striking capability to acquire and use iodine as a physiological adaptation to stress.

 

Organo-halogenation products have jumped 20-fold in the last 30 years.

 

 

 

 

 

Ecklonia is a genus of kelp and in the forefront of healing.

Ecklonia belong to the family Lessoniacea

Ecklonia species produce eckol-type phlorotannins

Ecklonia Cava and Ecklonia Bicyclis are two species of edible brown algae commonly harvested, which contain similar spectrum's of natural occurring constituents.

 

Differences lie in their polyphenol (phlorotannins) content.

Both species contain Eckol, Bieckol, Dieckol and Phlorofucofuroekol, however, the Bicyclis species also contains Phloroglucinol, Phloroglucinol Tetramer.

Ecklonia Bicyclis has a more diverse libarary of polyphenols and is therefore more comprehensive in the way it behaves as an antioxidant.

Ecklonia Cava, on the other hand, has less diversity in polyphenols but it also has higher concentrations of the polyphenols it does have

Both are extremely effective as antioxidants.

 

 

The Phaeophyceae or brown algae are a large group of sea weeds.

They litter beaches, rocks and bodies of water.

Brown algae play an important role in marine environments, both as a food source to the humans that inhabit the area but also for the habitats they become incorporated into.

 

Macrocystis, a kelp of the order of Laminariales, is a brown algae and the giant kelp (Macrocystis Pyrifera) forms underwater forests.

Kelp forests are underwater forests that trap the rays of the sun and use its energy to synthesize nutrients.

 

Brown algae contains the pigment fucoxanthin. Fucoxanthin is related to xanthin, the eye antioxidant. 

It is this pigment which is responsible for the algae's distinctive greenish-brown color

 

 

 

Other brown algae, grow along rocky seashores.

Kelp is saturated with nutrients that sustain the humans that feed off them.

Worldwide there are over 2000 species of brown algae
