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