Chemical and different nutritional characteristics of brown seaweed lipids

Abstract

Lipids are the fatty acid or their derivative which are insoluble in water but soluble in organic solvent. Brown color seaweeds have high value of total lipids (TL) contents, ranging from 10 to 18 % of dry weight. It contains glycoglycerol lipids (GL) as lipid class, which is rich in 18:4n_2, 20:5n_2 and 20:4n_5. Brown colored seaweed also contains fucoxanthin as a main functional compound. Its stable nature of oxidation is due to the presence of polyunsaturated fatty acids (PUFAs). Oxidative stability of brown seaweeds is very high. They also show ant obesity and anti-diabetic effects.
