Fats are the densest form of stored energy What are the fat-soluble vitamins? Fat-soluble vitamins: vitamins A, D, E, and K  Excess stored in body  Deficiencies slower to develop  Greater risk of toxicity What are Essential Fatty Acids? 1. Linolenic acid 2. Linoleic fatty acid The essential nutrients that are triglycerides, which are not created in the body: What is a phospholipid  Phospholipids are lipid compounds that form parts of cells walls and act as fat emulsifiers. It is similar to triglycerides, phospholipids contain fatty acids, but they have only two fatty acids, and the third spot contains a phosphate group. Molecules that makeup the cell membrane. Phospholipids are amphipathic molecules that make up the bilayer of the plasma membrane and keep the membrane fluid. A cell's plasma membrane contains proteins and other lipids (such as cholesterol) within the phospholipid bilayer. Best known as lecithin. What oils constitute monounsaturated fats? Monounsaturated Fatty Acid (oleic Acid) = olive oil, canola oil, peanut oil, safflower oil and This study source was downloaded by from CourseH on :55:11 GMT -05:00 This study resource was shared via CourseH Exam 2 nr228 Review sesame oil. Avocado How do Omega 3 fatty acids contribute to health? Main omega-3 fatty acid in fish is eicosatetraenoic acid ( EPA) derived from linolenic acid. Omega-3 fatty acids appear to lower the risk of heart disease by reducing the blood clotting process that can cause blockages in the arteries in the presence of plaques, reduce risk of myocardial infarction and reduce risk of sudden death( arrhythmias ). It reduces the risk of cardiovascular disease. What happens in fat catabolism?  Catabolism breakdown of lipids for energy involves the hydrolu=ysis of triglycerides into two-carbon units that become part of acetyl coenzyme A ( acetyl CoA) Acetyl CoA is an important intermediate by product in metabolism formed from the breakdown of glucose , fatty acids, and certain amino acids. What percentage of fat should be in the diet?  20 to 35 % of fat in the diet recommended by Dietary Reference Intakes ( DIs) What type of fat increases LDLs and decreases HDLs in the body? Trans fat raises the blood cholesterol component ( Low-density lipoproteins LDLs) that delivers cholesterol throughout the body and may contribute to plaque formation in arteries . Trans fat also decreases the blood cholesterol component ( high -density lipoproteins (HDLs) that removes excess and used cholesterol from the body. What compound distinguishes protein from other nutrients? Nitrogen What are the essential amino acids? How many?
