NUTR 30300 Chapter Notes - Chapter 5: Fish Oil, Lipoprotein, Chemical Substance
Document Summary
Lipids are energy dense: fatty acids from triglycerides contain more than twice the amount of calories per gram as protein and carbs. Consumption of common solid fats also contributes to the risk of cardiovascular disease. Lipids found in seafood (salmon) has been linked to lower risk for several chronic diseases. Lipids composed primarily of elements: carbon and hydrogen but have fewer oxygen atoms than carbs. Lipid is genetic term that includes triglycerides, phospholipids and sterols. Triglycerides-major form of lipid in the body and in food. Composed of three fatty acids bonded to glycerol. Phospholipids-any of a class of fat-related substances that contain phosphorus, fatty acids and a nitrogen-containing component. Sterols-compound containing a multi-ring (steroid) structure and a hydroxyl group (- Triglycerides are the most common type of lipid found in the body and in foods. Triglycerides contain 3 fatty acids bonded to glycerol. Fatty acid is a long chain of carbon bonded together and flanked by hydrogens.
