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