Hello!
I think this is going to be one of those unread questions that disappear into the abyss, so I'll shorten in hopes of a reply:
What exactly does this mean: "If the reaction is carried out in a glycine/hydrazine buffer pH0.9, then pyruvate is trapped as the hydrazone and H+ the buffer."?
I can't seem to find any straightforward information concerning this; or not at least I can follow...
Any help appreciated.
Thanks!

First of all - are you sure it is pH 0.9? Not pH 9.0?

Check what hydrazone is.
 
Sorry! Yeah it's pH 9.0. I'll have a look, but I am just about to post a more pressing question that I have.
