DISCIPLINE OF PHARMACEUTICAL CHEMISTRY DRUG DESIGN AND DISCOVERY BY: xxxxxxx Introduction A drug is a substance that we used mostly in our daily lives. It is a chemical substance with physiological effects when ingested or introduced into our bodies. The response produce can either be beneficial or harmful. Toxins and poisons can be classified as drugs. This report the term ‘drug’ is for medicinal or pharmaceutical purposes. Drugs used to prevent or treat diseases. Drug design

LEARNING LOG 2: Observe‚ Connect and Reflect on Your Learning PART III – Symmetry in Crystals The most striking examples of symmetry…are crystals. Herman Weyl Period Focus Image Question Your Observations Complete at the end of Week 5 Image 5 Uvarovite is a gemstone rich in chromium. What are your main observations about uvarovite symmetry from studying the external form? (30 - 40 words) (2 marks) What is your personal favourite gemstone and what is its space group. (up to

beaker that contained the filtrate and the filtrate was undisturbed until it had cooled to room temperature and when no more crystals had formed. 4. The beaker was placed in an ice-water bath for 10 minutes. 5. The crystals were collected by using a Hirsch funnel by vacuum filtration. The filter cake was then washed with 2 small portions of 0.5mL of cold water. The crystals were pressed dry as possible on the funnel with a spatula. 6. The melting point of recrystallized benzoic acid was determined

States of matter are the distinct forms that different phases of matter take on. Historically‚ the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions

TO QUESTIONS 1. How does the use of fluted filter paper hasten filtration? Why is it advisable to place a small piece of wire between the funnel and the mouth of the flask during hot filtration? Fluted filter paper is effective in preventing crystal formation in the filter paper. It is also often used in filtering hot saturated solution used during crystallization. One major advantage of a fluted filter is that it increases the speed of filtration. The crisscrossing of the folds help alleviate

The term ’powder’ really means that the crytalline domains are randomly oriented in the sample. Therefore when the 2-D diffraction pattern is recorded‚ it shows concentric rings of scattering peaks corresponding to the various d spacings in the crystal lattice. The positions and the intensities of the peaks are used for identifying the underlying structure (or phase) of the material. For example‚ the diffraction lines of graphite would be different from diamond even though they both are made of

Purpose: The purpose of our experiment was to determine the amount of water in copper sulfate pentahydrate expressed as a percent. Hypothesis: I think that bluestone crystals are 20% water‚ because it’s called pentahydrate (penta means five) and 1/5 of 100 (since it’s expressed as a percent) is 20‚ so I think bluestone crystals are 20% water. Procedure: The following list includes the materials and supplies we used in the experiment: 1) Crucible and Lid 2) Tongs 3) Alcohol Burner

made using the 40-pin AT89C52 microcontroller. This propeller display is mechanically scanned and displays the characters in digital format. Made from scrape it can be used anywhere and everywhere and the most amazing fact about the display is its crystal clear display. This display consists of just 23 bright LED’s which are rotated to show the display. For building the project‚ requirement 40 pin microcontroller and LED’s. this display can show the message‚ which will require a whopping 1504 LED’s

free to move past each other but still held together. Lastly there a solids which are molecules formed in a rigid formation which have a very strong attraction with repeating crystals and can only move in vibrations. Glass is none of the above‚ it is rigid like a solid‚ but its molecules are not arranged with repeating crystals which makes it amorphous like a liquid. "If you could preserve a window long enough‚ it might become a rigid puddle on the floor" (Ediger:1999‚Discover Magazine) Glass can

is that if I add different amounts of sugar to the same amount of boiling water and allow it to be cooled‚ than the one with the additional cup of sugar will be the one that grows more crystals. Therefore‚ the hypothesis was correct. The chosen glass to add the pure cane sugar did grow much more crystals at a more rapid pace. The purpose of the experiment is to grow a large amount of crystals on a wooden skewer. Rock candy is a candy made with sugar that to attempt to grow on a wooden skewer
