Lipids 2018
Download the book of abstractsFrom a chemical viewpoint, lipids are biological molecules that are insoluble in water but soluble in organic solvents. Within this broad definition, lipids are divided in a large number of types; including the most common ones listed as "oil", "fatty acid", "cholesterol" or "lecithin". Lipids are vital to life and are thus present in all living organisms as energy reserve and functional molecules, from animals to plants, as well as fungi and bacteria.
Scientific interest for lipids in environmental sciences has quickly increased in the last two decades. Recent research provided evidence that some lipids (and not only the well-known omega-3 EPA_eicosapentaenoic acid and DHA_docosahexaenoic acid) play essential roles in maintaining vital biological function that are related to the fitness components of marine organisms. In particular, lipids are key players in an organism’s ability to respond to and cope with environmental changes (temperature, light, salinity, nutrients, and pH). Yet, sources, biosynthesis pathways and functions of many lipids in marine organisms remain poorly described and understood. One of the aims of this multidisciplinary conference is to stimulate interdisciplinary discussions on concepts related to the role of lipids from lower up to higher trophic levels, serving both fundamental understanding but also socio-economic interests.
