Homework Help: Structure of molecules

  1. Jan 3, 2008 #1
    1. The problem statement, all variables and given/known data
    what is the difference between a steroid molecule, phopholipid, and fat molecule?


    2. Relevant equations
    discuss the general difference in their structures


    3. The attempt at a solution


    phospholipids are asymetrical with a hydrophilic head and a hydrophobic tail
    and the other two are symmetrical?

    I'm completely lost coz I dropped chemistry after two weeks of it, and now it's come back to haunt me in biology
