摘要：
We study the interaction of the guanidinium cation, a widely used protein denaturant, with amide groups, the common structural motif of proteins. Our results provide evidence for direct contact between guanidinium and similar to 2 amide groups, but the interaction is transient and weaker than for other cations with high charge-density.
