Phospholipids

... heads / hydrophobic tails is to form micelles, because this is the simplest structure that maximizes hydrophobic/philic interaction. In phospholipids, however, the hydrophobic tails have a greater cross-sectional area than the heads, and so they cannot form stable micelles - in other ...

So I asked other biology students in my class, and they said that just because the head is hydrophilic doesn't mean that it will dissolve. Also the head is attached to a hydrophobic fatty acid, which is another reason why it won't dissolve. Their answers make sense, but I'd like to know if that is t...

Why doesn't the hydrophilic head on the outside of a cell membrane dissolve? Being hydrophilic means that it is easily dissolved in water and/or has an affinity, so it would make sense to me that the head would dissolve in any solvent, so why doesn't it? Thanks for the help.

The majority of all the molecules in your body are ions (all phospholipids, almost all proteins, ATP, NAD+...) Of course many of these would be affected by any toxin to some degree, but I can't think of any reason why their ionic state would be important ...
