Hi! I'm just a little confused with respect to finding the pI of an amino acid with multiple charged groups. Which is correct? 1) The pI = the average of all the pKa values of each group (pka1+pka2+pka3/3) or 2) The pI = the average of the pKa values on either side of the zwitterion? If you could provide an example with the explanation I would REALLY appreciate it! Thanks!
Hey guys! I was just wondering if anyone had any good websites/notes/info they would recommend in terms of amino acids for the new mcat. I find I don't quite understand a lot of questions related to them (i.e: "what charge would lysine have in ph 7?"). I would appreciate any kind of info you have to offer, including anything about the characteristics of each amino acid (i.e: which can H bond?) Thank you!!!
