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