EPA and DHA are1 phospholipids. saturated fatty acids. phosphates. unsaturated fatty acids. 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. Carbon atoms cannot form rings; only long hydrocarbon chains like those found in fatty acids.1 True False “Hydrophillic” means:1 "makes water" "loves water" "splits water" "hates water" An unsaturated fatty acids has no double bonds in its hydrocarbon chain.1 True False 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. An electrically unbalanced molecule is called1 a proton. an ion. an acid. a hydroxyl. EPA and DHA are “good” fatty acids.1 True False The “tail” of a phospholipid is hydrophilic.1 True False How many bonds does Phosphorus usually want to make?1 2 5 4 3 1 Phosphate is negatively charged1 True False Phosphate is1 P02 PO4 P POH 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)
