Summary Introduction

To determine: The hydrogen bond donor and acceptor groups in asparagine.

Concept introduction: In general chemical formulation, a hydrogen bond is represented as D–H···A in which D–H is a hydrogen bond “donor group” and A is considered as the hydrogen bond accepter group or acceptor atom. Hydrogen bonds are basically characterized on the basis of structures by an H···A distance. This distance is shorter (at least 0.5$\stackrel{\circ }{\text{A}}$) than the calculated van der Waals distance, which represents the distance of the closest approach between two non-bonded atoms.
