Obesity, type 2 diabetes, and cardiovascular diseases are major problems in today's society, causing millions of deaths every year.

Thus, understanding how fatty acid metabolism works is of great importance in the battle against these diseases.

Abstract:
 This study primarily aimed to evaluate the usefulness of fatty acids (FAs) in revealing trophic relationships in Hong Kong wetlands, through a combination of field studies and laboratory experiments. A field-based study in Mai Po mangroves involved FA profiling of basal food sources (i.e., leaf litter from three mangrove species, diatoms and macroalgae, and sediments) and consumers (particularly crabs). FA composition of all mangroves was similar, and lacked some polyunsaturated FAs present in diatoms and macroalgae. Uca and Sesarma crabs, with different feeding mechanisms, had divergent

Abstract:
Alors que les ressources fossiles décroissent, le concept de bio-raffinerie est une approche très attrayante pour la production de produits chimiques à partir de ressources renouvelables. Dans ce contexte, les dérivés d’acides gras insaturés, obtenus par hydrolyse de triglycérides issus de végétaux, sont une catégorie importante de substrats. Leur conversion en composés à haute valeur ajoutée est un objectif majeur qui peut être atteint grâce à la catalyse, et plus particulièrement grâce à la métathèse des alcènes. De plus, dans un esprit de meilleure séparation entre produits et catalyseurs,

Le méthane (CH4) est un puissant gaz à effet de serre produit lors de la fermentation microbienne anaérobie des aliments dans le rumen. L’un des enjeux majeurs pour le secteur de l’élevage est de trouver des stratégies (alimentaires, génétique) pour réduire les émissions de CH4 tout en maintenant les performances animales. Les techniques de mesure de ces émissions sont coûteuses et difficilement utilisables à grande échelle sur le terrain, d’où la nécessité de trouver des alternatives de mesure ou biomarqueurs pour prédire ces émissions.

Abstract:
The aquaculture industry is expanding to supply the demand for sustainable protein, essential nutrients, and energy. Recent reports of worldwide fish production indicate a rise in aquaculture, coupled with near static capture fishery landings. Feed prices represent a major limiting factor for aquaculture as ingredients sourced from wild caught fisheries remains stagnant. Fish oil is included in the realm of expensive, marine sourced ingredients and is a highly nutritious commodity. Lipids are indispensable constituents of aquafeeds because they provide essential energy and nutrients. Some fatt

Abstract:
An increased interest in functional beverages is occurring, and omega-3 fatty acids (FA) are one of the most commonly sought ingredients to fortify such beverages. Omega-3 FA produce beneficial health effects, likely due to their anti-inflammatory properties. The majority of current omega-3 FA-fortified products include marine-derived omega-3 FA sources, often producing undesired flavors due to lipid oxidation. Little research regarding incorporation of alpha-linolenic acid in functional beverage formulation has been conducted. Alpha-linolenic acid is less susceptible to oxidation and may

Altered fatty acid (FA) biosynthesis and metabolism have been related to enhanced cellular growth and proliferation of cancer cells. The membrane FA composition may influence its properties and membrane lipid-related signaling. The first part of this thesis aimed at the in vitro evaluation of the effects of a novel copper complex, [Cu(TPMA)(Phenanthroline)](ClO4)2, on cell viability and membrane fatty-acid lipidome. The complex was studied as a free compound or under an encapsulated form within polymeric nanoparticles in neuroblastoma (NB100) and breast carcinoma (MCF7) cell lines. In both cel
