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