Secondary hydrogen bond

Secondary hydrogen bond

Introduction

Hydrogen bonding interaction in proteins plays a crucial role in protein folding, dynamics and function. The locally ordered structure, the so-called secondary structure of a protein is created by hydrogen bonding within the protein backbone. These hydrogen bonds have structural role in the proteins and called secondary hydrogen bonds cite journal|author= Bikadi Z, Demko L, Hazai E| title=Functional and structural characterization of a protein based on analysis of its hydrogen bonding network by hydrogen bonding plot| journal=Arch Biochem Biophys.|date=2007| volume=461 |issue=2 |pages=225–234 |doi=10.1016/j.abb.2007.02.020 ] .
