Chemical Sketch Tool - RCSB PDB
Use the Chemical Sketch tool to draw or edit a molecule. The resulting SMILES or InChI string may be used to search for matching molecules in the PDB Chemical Component Dictionary. Note that matches will include any chemical component in the dictionary, including polymeric ones like Alanine or Adenosine. Help.
Chemical Structure - Introduction, Types, Examples and …
Chemical Structure is the spatial arrangement of atoms in a molecule. Chemical structure determines the molecular geometry of the molecule. Russian Chemist Alexander Butlerov acknowledged that molecules are not random clusters of atoms and functional groups but are arranged in a concrete pattern.
Chemical structure - Wikipedia
A chemical structure of a molecule is a spatial arrangement of its atoms and their chemical bonds. Its determination includes a chemist 's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid.
1.12: Drawing Chemical Structures - Chemistry LibreTexts
The three different ways to draw organic molecules include Kekulé Formulas, Condensed Formulas, and Skeletal structures (also called line-bond structures or line formulas). During this course, you will view molecules written in all three forms.

Chemical Structures - Wolfram|Alpha
Chemical structure is determined by the three-dimensional network of bonds between atoms in a molecule. Use Wolfram|Alpha to visualize structures in 3D with a space-filling model, where atoms are shown as spheres proportional to their van der Waals radius; with a ball-and-stick model; or as a skeletal structure.
