Homework Help: Lysine Basic/Nonbasic Hydrogens

Posted by Kim on Friday, June 5, 2009 at 10:45pm.

For the amino acid Lysine, the nitrogen with the H attached to it is not basic (since you can draw out the resonance for it). But the other nitrogen that has a double bond is not basic. Why is this?? I can draw out the resonance for the double bonded nitrogen as well.. so shouldnt it be considered nonbasic as well. can someone please explain this to me? Thanks
