      At http://library.thinkquest.org/C004535/c … ranes.html it states that "Many of the membrane-associated proteins have hydrophilic and hydrophobic regions. The hydrophilic regions are used to help anchor the protein inside of the cell membrane."

      I am new to this subject (and a senior, not doing homework) but the second sentence sounds counter-intuitive to me because the interior of the lipid membrane contains the hydrophobic tails of the lipids. So why – or how could they – would "membrane-associated proteins" utilize "hydrophilic regions" to anchor themselves in a hydrophobic environment?

      I found my answer here:

      I would guess it’s mistake and should be hydrophobic 😉
