In vitro antithrombotic properties of salmon (salmo salar) phospholipids in a novel food-grade extract
peer-reviewed Marine and salmon polar lipids (PLs) extracted by conventional extractions with non-food-grade solvents (CE-salmon-PLs) possess antithrombotic bioactivities against platelet-activating factor (PAF) and thrombin. Similar effects of food-grade-extracted (FGE) marine PLs have not yet been...
