Fatty acid fatty acid composition in sea cucumber; Holothuria atra and Holothuria ocellata at Pantai Teluk Bidara, Dungun, Terengganu

Abstract

Fatty acids (FA) biomarkers analysis was done to determine the fatty acids composition and to investigate the food sources materials for the sea cucumbers. The analysis was done to examine the lipid content and to compare the fatty acid composition in two species of sea cucumber, Holothuria atra and Holothuria ocellata from Pantai Teluk Bidara, Dungun, Terengganu. The fatty acid profile from extract of sea cucumber and sediment was determined using gas chromatography (GC) technique. The lipid was extracted in mixture of chloroform:methanol. The total lipid content is high in H atra (0.056 g g-1) compared to H ocellata (0.043 g g-1 ). The total fatty acid concentrations vary in each sample, where the highest is in H. atra ( 4.471 µg g-1) and lowest in H ocellata (1.154 µg g-1).
