~SMILES~

Assalamualaikum w.b.t...

Hi!How are you guys???
Frankly,we are not seeing with each other for a long time..;)

Do you have any idea about what I am going to share with you today?

In today class,we have learned about SMILES (Simplified Molecular Input Line Entry System)...It is a specification for unambiguously describing the structure of chemical molecules using short ASCll strings. Besides that, SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules. It is quite interesting...Let us look at the examples below...^_^

Drawing Chemical Structures And Graphical Images



Bismillahirrahmannirrahim...
Assalamualaikum w.b.t...

Hi,we meet again!!

Last time,for KOS 1110 class,our beloved Madam Noraslinda has taught us on how to use the ACD/ChemSketch software.Frankly, it is an integrated software package from Advanced Chemistry Development, Inc., (ACD/Labs) for drawing chemical structures, reactions, and schematic diagrams, and designing other chemistry-related reports and presentations.Of course ,it helps us drawing the chemical structure and graphical images more and more easier.Ok,let us take a look now!!

Simple Structure

This chapter considers the basics of structure drawing,which give us an overview of the chemical drawing features of ACD/ChemSketch . We are able to draw atoms, bonds (single double, triple, wedge, coordination, undefined,and Markush), as well as labels and polimers. Here, is the example of simple structure :


Complex Structure

Next, in this chapter ,we have learnt on how to draw more complex structures using the advanced tools of ACD/ChemSketch.We are able to use the Table of Radicals to draw typical chemical fragments.Besides that,we also have taught on how to quickly draw ring structures ,delete and replace atoms, set double and triple bonds, set an atom's charge, draw cations and anions, and change various atomic properties too. Here, are the example of complex structure :




Creating Graphical Objects

On the other hand, this chapter familiarizes us with the creation of graphical objects. We have learnt about how to use Draw mode tools for creating various types of graphical objects. Here, are the examples of graphical images :

The Energy Of Reaction Diagram

Various Types Of Orbitals



Vacuum Distillation Apparatus


A Two-Chain DNA Strand




Lipids And Micelles



That's all from me for this time. Hope to see you again next time.Wassalam...
