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).
