Slide Number 1

Title Slide

Hello everyone.

Welcome to this tutorial on Analysis of Compounds in GChemPaint.

Slide Number 2

Learning Objectives

In this tutorial, we will learn about,
  • Molecular contextual menu
  • Save the molecule in .mol format
  • Add and edit a reaction
  • Add reaction conditions and reagents on the reaction arrow
  • Convert reaction molecules into 3D
Slide Number 3

System Requirement

For this tutorial I am using

Ubuntu Linux OS version 12.04.

Select Molecule; a contextual menu opens alongside.

Point to the menu items. Contextual menu contains different menu items, of which, I will discuss about-
  • NIST WebBook page for this molecule
  • PubChem page for this molecule and
  • Open in Calculator
Click on NIST WebBook page for this molecule Click on NIST Web page for this molecule
Move the cursor over the page. Alanine's NIST webpage opens.

Webpage shows all the details about Alanine.

Right click on Alanine to open PubChem page for this molecule.

Come back to GChemPaint editor.

Come back to GChemPaint editor.

Right click on Alanine to open the PubChem page for this molecule.

Point to the structure on the webpage. Click on Alanine structure on this webpage.

A new web-page with 2D Structure and 3D Conformer tabs, is seen.

Click on 3D Conformer tab to view the structure in 3 dimension Click on 3D Conformer tab to view Alanine in 3 dimensions.
Click on the 3D structure. Click on the displayed 3D structure.

This opens the structure in a separate window with some controls on the top and on the left.

Click on the Rotation icon Click on the Rotation icon to rotate the structure in various directions.
Click on H icon

Point to the Hydrogen atoms in white.

On the same page, click on H icon to show hydrogens.

These are the Hydrogens.

Switch to GChemPaint. Let's switch to GChemPaint window again.
Right click on Alanine to Open in Calculator.

Move the cursor on Chemical calculator window.

Right click on Alanine; choose the option Open in Calculator.

Chemical calculator window opens.

If not, please install the same, using Synaptic Package Manager, as in the Overview tutorial.

Point to the tabs. This Window has two tabs at the bottom - Composition and Isotopic Pattern.
Move the cursor to all the components one by one. Composition tab has the following components-
  • Formula
  • Raw formula
  • Molecular weight in g.mol-1 ( gram.mole-inverse)
  • Compound's elemental mass percentage(%) analysis.
Click on Isotropic Pattern tab.

Point to the graph and the peak.

Click on the Isotropic Pattern tab.

It shows a graph of mass spectrum with a peak at Molecular weight of the compound.
