LIPIDOMICS AS A NEW APPROACH FOR UNRAVELING THE POLAR LIPID COMPOSITION OF CHONDRUS CRISPUS

Lipids are major components of marine organisms, which have a unique lipid composition. However, identification of lipid profile of marine organisms in not fully elucidated and their potential is waiting to be explored. So far marine organisms (e.g. fish, seafood, macroand microalgae) and marine-derived natural products (e.g. fish oil) are an endless source of lipids with many beneficial effects on human health. Lipids such as polyunsaturated fatty acids are valuable nutrients while others such as glycolipids are considered promising bioactive natural products with potential therapeutic applications such as anti-inflammatory, anti-proliferative, antioxidant and antimicrobial. Different marine organisms have a typical lipid profile representing the marine chemical biodiversity. Lipid composition is very sensitive to environmental conditions, and also to the nutritional support. This feature allows the manipulation of environmental conditions in order to improve the production of bioactive natural compounds, but the identification of a specific lipid signature is still a challenge. Lipidome of eukaryotes comprises thousands of lipids that are structurally and functionally diverse. In the last years, the most recent advances of mass spectrometry associated with high sensitivity, and capability of high throughput analysis have been opening new perspectives in the understanding of the role of lipids in marine organism’s biochemistry. In this lecture, the most common analytical strategies based on mass spectrometry analysis used in marine lipidomics will be briefly presented, as well as how it can be used to fully explore the potential of the sea as a source of addedvalue products.
