There are many different kinds of omega-3 fatty acids.1 True False How many bonds does Phosphorus usually want to make?1 2 1 4 3 5 The part of the phospholipid that is hydrophobic is the1 "tail". phosphate. "head". “Hydrophillic” means:1 "hates water" "splits water" "loves water" "makes water" Water molecules are attracted to the phosphate head of the phospholipid.1 True False EPA and DHA are1 saturated fatty acids. phospholipids. phosphates. unsaturated fatty acids. Carbon atoms cannot form rings; only long hydrocarbon chains like those found in fatty acids.1 True False Phosphate is1 POH PO4 P P02 Phosphate is negatively charged1 True False A very basic phospholipid molecule is composed of1 a glycerol, a phosphate, and two fatty acids. a phosphate and a fatty acid. a glycerol, 2 phosphates, and a fatty acid. a phosphate and two fatty acids. An electrically unbalanced molecule is called1 a proton. an acid. a hydroxyl. an ion. An unsaturated fatty acids has no double bonds in its hydrocarbon chain.1 True False The “tail” of a phospholipid is hydrophilic.1 True False EPA and DHA are “good” fatty acids.1 True False 3: Lipids and glycerol 5: Membranes (part 1) Back to: 4: Lipids (part 2: Phospholipids)
