EPA and DHA are “good” fatty acids.1 True False The part of the phospholipid that is hydrophobic is the1 "head". phosphate. "tail". How many bonds does Phosphorus usually want to make?1 3 2 5 1 4 A very basic phospholipid molecule is composed of1 a phosphate and two fatty acids. a phosphate and a fatty acid. a glycerol, a phosphate, and two fatty acids. a glycerol, 2 phosphates, and a fatty acid. Phosphate is:1 POH P02 P PO4 The “tail” of a phospholipid is hydrophilic.1 True False An unsaturated fatty acids has no double bonds in its hydrocarbon chain.1 True False EPA and DHA are1 unsaturated fatty acids. saturated fatty acids. phosphates. phospholipids. Phosphate is negatively charged.1 True False “Hydrophillic” means:1 "hates water" "splits water" "loves water" "makes water" An electrically unbalanced molecule is called1 a hydroxyl. an acid. a proton. an ion. 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 Carbon atoms cannot form rings; only long hydrocarbon chains like those found in fatty acids.1 True False 3: Lipids and glycerol 5: Membranes (part 1) Back to: 4: Lipids (part 2: Phospholipids)
