*carboxyl

It's obviously not the last choice.

I figured as much

abb0t · Answer

Well, usually loss of water is the product (hydrolysis) during peptide formation. So you have a peptide, but I don't think you have enuff peptides to actually call it a peptide, because I think it's 2 or 3+ so I'm going to argue choice 2.

Thank you, that helped a lot. :)

abb0t · Answer

sorry, enough peptides to call it a polypeptide* is what i MEANT to say.
