4: Lipids (part 2: Phospholipids) Quizellenjmchenry2019-06-26T19:01:15-04:00 Please sign up for the course before taking this quiz. “Hydrophillic” means:1 "loves water" "makes water" "splits water" "hates water" An unsaturated fatty acids has no double bonds in its hydrocarbon chain.1 True False Carbon atoms cannot form rings; only long hydrocarbon chains like those found in fatty acids.1 True False Phosphate is negatively charged1 True False An electrically unbalanced molecule is called1 an ion. a hydroxyl. an acid. a proton. The part of the phospholipid that is hydrophobic is the1 "tail". "head". phosphate. The “tail” of a phospholipid is hydrophilic.1 True False Phosphate is1 P02 PO4 POH P How many bonds does Phosphorus usually want to make?1 2 1 5 4 3 A very basic phospholipid molecule is composed of1 a phosphate and two fatty acids. a glycerol, 2 phosphates, and a fatty acid. a glycerol, a phosphate, and two fatty acids. a phosphate and a fatty acid. EPA and DHA are “good” fatty acids.1 True False EPA and DHA are1 saturated fatty acids. phosphates. phospholipids. unsaturated fatty acids. Water molecules are attracted to the phosphate head of the phospholipid.1 True False There are many different kinds of omega-3 fatty acids.1 True False 3: Lipids and glycerol 5: Membranes (part 1) Back to: 4: Lipids (part 2: Phospholipids)
