Background: "Siasia" is a seaworm species in the phylum that includes Sipuncula Sipunculidea class. This animal has been consumed for generations by coastal communities Nusalaut Island, central mollucas but not yet universally known. Until now there has been obtained gisi complete composition. This study aimed to identify the composition of fatty acids contained in vain fresh seaworms. Methods: Seaworms vain taken from coastal waters of Negeri Titawaai and Nalahia Nusalaut Island, Central Moluccas in March 2014. The parameters analyzed include methods is sokhlet fat content and fatty acid by GC method. Results: The results showed fresh siasia fat content 1.12% of coastal waters Titawaai while 1.91% of coastal waters Nalahia. Fatty acids seaworms were identified from coastal waters Titawai  is  kaparat acid (C10: 0), lauric acid (C12: 0), myristic acid (C14: 0), palmitoleic acid (C16: 1), stearic acid (C18: 0), linolenic acid (C18: 3) acid and eicosapentaenoic (C20: 5) while the fatty acids of  seaworm vain of coastal waters Nalahia include is lauric acid (C12: 0), myristic acid (C14: 0), palmitoleic acid ( C16: 1), stearic acid (C18: 0) and eicosapentaenoic acid (C20: 3). Conclusion: The fat content of fresh siasia sea worms is 1.12% from the waters of Titawaai beach, while 1.91% of the waters of the coast of Nalahia.

Main Fatty Acid

The deep red colour of the fruits of Palisota barteri results from a high content of Carotenoids. The main pigment now has been identified as β-Citraurin. It is esterified with the saturated fatty acids from C4, C6 ... up to C18. The main fatty acid is lauric acid. Minor pigments are Zeaxanthin and Cryptoxanthin, both esterified in the same manner as β-Citraurin, and β-Apo-8′-carotinal, β- and ξ-Carotin and a very small amount of Lycopin.

A stable form-phase change materials (PCM), based on capric-lauric acid eutectic served as the absorption material and the support of nano-silica material to prepare by sol-gel method. The best ratio capric-lauric acid eutectic combination is determined for 60 wt. %. Capillarity because of the influence of the hydrogen bonding, fatty acid and eutectic can be fixed in the three dimensional network structure of the construction of the silicon atom bonds and O still so solid sample melting point composite heating more fatty acid eutectic. Form and chemical properties of the composite phase change the transmission electron microscope, semi and Fourier transform infrared method.- Differential scanning calorimetric hot method is used for measuring phase transition temperature and phase change of latent heat composite, value 19.57 and 71.28 J/g , respectively. At the same time, service performance and other composite material thermal stability and thermal conductivity coefficient test using thermo gravimetric analysis and transient hotline method, respectively.

The effect of Ca supplementation on the methane-suppressing effect of lauric acid was investigated in an experiment based on a 2 × 2-factorial arrangement using the in vitro system Rusitec. Additional Ca was supplemented at 1 g kg-1 diet in the form of compounds of relatively low solubility in rumen fluid. Lauric acid (C12:0), the predominant effective medium-chain fatty acid in coconut oil, was added at a level of 50 g kg-1. Adding C12:0 did not affect bacterial count, but eliminated ciliate protozoa from fermenters. Ammonia concentration in fermentation mixture declined and volatile fatty acid pattern changed with C12:0. The apparent degradation rate of total organic matter was not altered by C12:0, but fiber fermentation was depressed (P < 0.001). Effects of Ca on microbial counts and fermentation characteristics remained low. Without additional Ca, C12:0 reduced the average daily methane release (mmol g-1 organic matter degraded) by 76%. In comparison, C12:0 only reduced methane production by 47% when additional Ca was included in the diet (interaction of C12:0 and Ca, P < 0.05). The present results suggest that the dietary content of soap-forming Ca has to be kept low in order to achieve a high methane-suppressing effect of lauric acid.

The effects of ethanolamine, choline, and different fatty acids on phospholipid synthesis via the CDP-ester pathways were studied in isolated rat intestinal villus cells. The incorporation of [14C]glucose into phosphatidylethanolamine was stimulated severalfold by the addition of ethanolamine and long-chained unsaturated fatty acids, while the addition of lauric acid inhibited the incorporation of radioactivity into phosphatidylethanolamine. At concentrations of ethanolamine higher than 0.2 mM, phosphoethanolamine accumulated, but the concentration of CDP-ethanolamine and the incorporation of radioactivity into phosphatidylethanolamine did not increase further. The incorporation of [14C]glucose into phosphatidylcholine responded in a way similar to that of phosphatidylethanolamine, except that a 10-fold higher concentration of choline was required for maximal stimulation. CCC inhibited the incorporation of choline into phosphatidylcholine. In contrast with hepatocytes, villus cells did not form phosphatidylcholine via phospholipid N-methylation. The data indicate that, in intestinal villus cells, the cytidylyltransferase reactions are rate limiting in the synthesis of phosphatidylethanolamine and probably also of phosphatidylcholine. The availability of diacylglycerol and its fatty acid composition may also significantly affect the rate of phospholipid synthesis.
