Re: Phospholipids

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...

Here an analogy to help you understand: Take your name signature (cursive) for both last and first name. First level: straighten the signature and you get two lines, which would be the polypeptide (peptide chain). Second level: take the line and start arranging it by bending and folding it to your s...

Thanks for the help.
