NUTR 200 Lecture Notes - Lecture 13: Trans Fat, Digestion, Safflower
Document Summary
List some important biological funcions of fat in the body. Name and recognize the chemical structure of the major dietary lipids. Deine eicosanoids and indicate the faty acids from which they are. Name the most prominent cellular locaion of phospholipids. Energy: energy dense, energy storage, energy during rest and during exercise, used for energy during prolonged exercise, especially ater glycogen is depleted. Fat is essenial to many body funcions: cell membranes, nerve cells, protecion, insulaion. Fat-soluble vitamins: required for their absorpion and transport. Fat in foods: provides lavor and texture. Lipids - diverse class of molecules - insoluble in water. Three types of lipids are found in foods and in body cells and issues: Phospholipids = 2 faty acids, a phosphate molecule + glycerol. Saturated hydrogen atoms surrounding every carbon in the chain. Meats and tropical palm oils: monounsaturated lack hydrogen atoms in one part ( one double bond) olive and canola oils.
