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