...SMILES... : )

In the last class of KOS1110 we learned about SMILES.

SMILES-Simplified Molecular Input Line Entry Specification.
-is a specification for unambiguously describing the structure of
chemical molecules using short ASCII strings.

We did SMILES practice using ChemSketch to get SMILES notations.
This practice was very difficult because we should draw complicated chemical structures.

Some of the results are:

PDB(Protein Data Bank)..

PDB is a repository for 3-D biological macromolecular structure.
It includes:
-protein
-nucleic acids
-viruses

Obtained by:
-X-Ray crystallography(80%)
-NMR spectroscopy(16%)

Commonly used software
-pdb_extract
-ADIT
-PDB Validatuon Suite

ChemSketch is very....

Today i learn about drawing chemical structures and graphical images..
As usual,our madam gives us a task which we must completed it during the class hour..
The tasks is:
-Drawing simple structures
-Drawing more complex structure
-Creating graphical object.
1.drawing the energy of reaction diagram.


2.drawing differents kind of orbitals



3.drawing vacuum distillation apparatus



4.drawing a two-chain DNA strands

5.drawing lipids and micelles

Thus,i hope what i learn today will give many benefits to me in the future.

Thanks to madam and all my friends who help me to do this tutorial..

ChemSketch is very enjoyful..
