3: Lipids and glycerol Quizellenjmchenry2019-06-26T19:04:05-04:00 Please sign up for the course before taking this quiz. What is a good source of oleic acid?1 olive oil bone marrow butter coconut oil What is required to attached a fatty acid to a glycerol?1 a special enzyme scissors and glue a water molecule nothing What common household item is glycerol most like?1 sock hanger sponge spoon What molecule can attach to one, two, or three fatty acids?1 the carboxyl group long chains of carbon atoms nitroglycerin glycerol How many fatty acids does a diglyceride have?1 1 0 3 2 What is the process called when two molecules are joined together by taking an OH off of one molecule and an H off of the other, and form water as a byproduct?1 dehydration synthesis covalent bonding hydrogen bonding dehydration Which of these words is actually related to the “lin” in linoleic acid?1 lion line linen linoleum Which of these fatty acids is the shortest?1 oleic acid stearic acid lauric acid palmitic acid What do you call fatty acids that our bodies cannot make but must get from food?1 unsaturated fatty acids essential fatty acids saturated fatty acids triglycerides Which of these statements has nothing to do with why unsaturated fatty acids look bent at the end?1 Hydrgogens hate to be next to each other and move as far apart as possible. Some hydrogen atoms are "missing." Dehydration synthesis took place. There is a double bond where the bend is. Does glycerol ALWAYS have three fatty acids attached to it?1 Yes No Does it matter if you have a lot of triglycerides floating around in your blood?1 No Yes Which are liquids at room temperature?1 unsaturated fats saturated fats What makes a saturated fatty acid saturated?1 It is a liquid at room temperature. Each carbon atom has all the hydrogen atoms it can possibly hold. It has a COOH at the end. The carbon chain has lost some hydrogen atoms. What kind of cell stores triglycerides?1 skin cells muscle cells nerve cells fat cells Which part of a fatty acid is the acid part?1 COOH (carboxyl group) chain of carbon atoms neither both How many carbon atoms are in a glycerol molecule?1 3 6 1 2 What is another word for glycerol?1 nitroglycerin glyphosate glycerin glucose Where do you find a lot of palmitic acid?1 In palms but also in human fat cells. Only in plants such as palms and coconuts. In olive oil. What does the 3 mean in an omega-3 fatty acid?1 It has 3 oxygen atoms. It is part of a triglyceride and tri means 3. The double bond is the 3rd carbon up from the bottom. It has 3 missing hydrogens. 2: Carbon atoms and fatty acids 4: Lipids (part 2: Phospholipids) Back to: 3: Lipids and glycerol
