What is ACD/ChemSketch ACD/ChemSketch is a chemical drawing software package from Advanced Chemistry Development, Inc. designed to be used alone or integrated with other applications. ChemSketch is used to draw chemical structures, reactions and schematic diagrams. It can also be used to design chemistryrelated reports and presentations. ACD/ChemSketch has the following major capabilities: · Structure Mode for drawing chemical structures and calculating their properties. · Draw Mode for text and graphics processing. · Molecular Properties calculations for automatic estimation of: * molecular weight; * percentage composition; * molar refractivity; * molar volume; * parachor; * index of refraction; * surface tension; * density; * dielectric constant; and * polarizability. ACD/ChemSketch can stand alone as a drawing package or act as the “front end” to other ACD software such as the NMR Predictor engines.

The PDB archive contains information about experimentally-determined structures of proteins, nucleic acids, and complex assemblies. As a member of the wwPDB, the RCSB PDB curates and annotates PDB data according to agreed upon standards.
The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists.
Lon ATP-dependent proteases are key components of the protein quality control systems of bacterial cells and eukaryotic organelles. Eubacterial Lon proteases contain an N-terminal domain, an ATPase domain, and a protease domain, all in one polypeptide chain.

1) Recite and ponder on the meanings of the Quran. Tranquillity then descends and our hearts become soft. To get optimum benefit, remind yourself that Allah is speaking to you. People are described in different categories in the Quran; think of which one you find yourself in.
2) Realize the greatness of Allah. Everything is under His control. There are signs in everything we see that points us to His greatness. Everything happens according to His permission. Allah keeps track and looks after everything, even a black ant on a black rock on a black moonless night.
3) Make an effort to gain knowledge, for at least the basic things in daily life e.g. how to make Wudu properly. Know the meanings behind Allah's names and attributes. People who have Taqwah are those who have knowledge.
4) Attend gatherings where Allah is remembered. In such gatherings we are surrounded by angels.
5) We have to increase our good deeds. One good deed leads to another good deed. Allah will make the way easy for someone who gives charity and also make it easy for him or her to do good deeds. Good deeds must be done continuously, not in spurts.
6) We must fear the miserable end to our lives; the remembrance of death is the destroyer of pleasures.
7) Remember the different levels of akhirah, for instance when we are put in our graves, when we are judged, whether we will be in paradise or hell.
8) Make Dua, realize that we need Allah. Be humble. Don't covet material things in this life.
9) Our love for Subhana Wa Tuala must be shown in actions. We must hope Allah will accept our prayers, and be in constant fear that we do wrong. At night before going to sleep, we must think about what good we did during that day.
10) Realize the effects of sins and disobedience- one's Iman is increased with good deeds and our Iman is decreased by bad deeds. Everything that happens is because Allah wanted it. When calamity befalls us- it is also from Allah. It is a direct result of our disobedience to Allah.
Aisha, the wife of Allah's Apostle (May peace be upon him), reported Allah's Apostle (May peace be upon him) as saying:
Kindness is not to be found in anything but that it adds to its beauty and it is not withdrawn from anything but it makes it defective.
Narrated in Sahih Muslim, Book 3, Number 6274
