Protein Data bank/RasMol

This post is about using pdb (protein data bank) which contains information regarding structures of protein, nucleic acid, and complex assemblies. Then, I use another software called RasMol in order to view the structure in 3D. We can actually view the structure in different type of display and colour depending on what we want to focus about.

Here is the example of a protein structure:

For the next post, we learned about SMILE which stands for Simplified Molecular Input Line Entry Systems. SMILES is another way on how to represent the atoms of a molecule in a simple way.

Two examples of structures with its SMILE notation:


We learn how to draw graph using excel.

Using Excel to draw linear graph (straight line)

Using Excel to draw polynomial graph


For this post, these are some examples of drawing that I made using Chemsketch.

For this post, I have to tell about Maple...not maple syrup disease or maple syrup that we eat with the pancake..but it is a math and engineering software that is an essential tool for mathematics and modelling...

Actually, I don't want to talk about the software but my experience in learning the Maple...For those who want to know some basic thing about this software, you can go to this website.

These are some of the snapshots about maple:

Maple interface

Maple interface

For me, learning Maple is like learning HTML...we have to remember the command and do a lot of exercise to get used to it...only then we can master the Maple..

Some of the command in maple are:

Command Description
evalf evaluate using floating-point arithmetic
exp evaluate using floating-point arithmetic
eval evaluation
restart clear internal memory

Thank you for reading...
