چکیده

Lipids typically exist in a state in which various fatty acids are bound to a backbone such as glycerol, sphingosine, cholesterol, etc. With recent advances in analytical techniques, especially those associated with mass spectrometry, identification of lipid components, including their molecular species, is becoming possible. However, it is still difficult to identify all the components of lipids. Fatty acids, as mentioned above, are a major component of lipids, and obtaining information on the fatty acid composition of all the lipids contained in a biological sample is a critical step in comprehensive lipid analysis. An effective approach to analyzing fatty acid content is to apply gas chromatography/mass spectrometry (GC/MS) to the analysis of the constituent fatty acids of derivatized methyl esters.

Seasonal Changes in the Content and Composition of Lipids in Acropora downingi

The lipid content and composition of the reef-building coral Acropora downingi, the largest coral reef of Hengam Island, were examined throughout a year. The results showed that the lipid content of A. downingi significantly differs in different seasons (t-test, P< 0.05). Depending on the season and spawning times, the lipid content of A. downingi ranged from 16.5 to 37.7 % (dry weight). The to...

Determination and study the fatty acid contents and their seasonal variations by temperature of a dominant bivalve(Callista umbonella) of Haleh Creek

In this study fatty acid contents, because of the importance in human’s life, and their seasonal variations of a dominant bivalve of Haleh Creek were determined for the first time. Fatty acid identification was done by GC-MS (Gas Chromatography–Mass Spectrometry) method. After collecting and dissecting the species from the shells, samples weighed and frozen for further experiments. All the samp...
