Proton affinities of polyglycines assessed by using the kinetic method.

Z Wu1, C Fenselau.   

Abstract

The proton affinities of a series of peptides, chosen to show the effects of chain length, were measured by the kinetic method using amines as standard reference bases. Proton affinities of polyglycines with residues ranging from 2 to 10 were measured and the values were found to increase as the number of residues increases.
