Interpretation Introduction

Interpretation:

The confirmation of polypeptide flavodoxin has to be checked whether it has helical or sheet-like confirmation based on the given values.

Concept Introduction:

Karplus equation:

The magnitude of 3JHH in an HCCH group depends on the dihedral angle, ϕ between the two C-H bonds.  The variation is given by Karplus equation as follows,

3JHH=A+Bcosϕ+Ccos2ϕwhere,J-couplingconstant
