1. The problem statement, all variables and given/known data Phospholipids have headgroups and hydrocarbon chains as follows: A. amphipathic, non polar B. non polar, polar C. polar, non polar D. charged, non polar 2. Relevant equations phospholipids have a phosphate head group and fatty acid residue hydrocarbon tails. 3. The attempt at a solution I have eliminated A and B as they are obviously incorrect. I would classify phospholipid heads as being both charged, and (thus) polar. C and D seem to be, both, correct answers to me. But of course there should be only one.
