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