Abstract
A comparative study of various types of lipids in a coral Pocillopora damicornis and a sponge Acanthella carteri was carried out. Samples were collected from the Obhur Creek of the Jeddah coast. The lipids were separated by column chromatography on silica and the individual class of lipids was estimated using standard procedures of spectroscopy. It was observed that phospholipids were the dominant in both the organisms (approximately 50% of the total lipids) followed by sterol lipids (9.50 mg g‑1 in sponge and 2.70 mg g‑1 in the coral. Triglycerides were found to be more in the sponge compared to coral (6.85 mg g-1 and 1.90 mg g-1, respectively). However glycolipids were higher in coral (1.30 mg g‑1) compared to the sponge (0.45 mg g-1). The total lipids in the sponge were found to be higher compared to the coral.
