How does glycine act as a proton acceptor? I read that H can dissociate from O in a solution, so therefore that makes it able to be a proton acceptor, but what does this mean? How do you go about thinking if something can be a proton acceptor?

Almost any molecule with lone pairs can act as a proton acceptor. Smaller, less electronegative atoms (or atoms with negative formal charges) make the best proton acceptors. For glycine, the -NH2 group has a lone pair that easily accepts an electron.
