This is a lab in which we will be using combustion to make magnesium and turn into a fine powder. We will first put the crucible on a mesh above bunser burner to heat it up to get out any moisture. We will then record the weight and weigh the magnesium in the crucible. Then we will put the crucible over a flame with the magnesium inside until it turns into the powder. There are many changes in the world. These changes are like changes in chemistry because some you don’t see and there is some

The desired starting compound 3- N-amino -2, 5, 6- trimethyl thieno[2,3-d]- pyrimidin(3H)–4-one [RJ-1] was prepared from ethyl methyl ketone and ethyl cyano acetate, followed by the treatment of the product with acetic anhydride and hydrazine hydrate. RJ-1 was then treated with various substituted aryl aldehydes to get a new series of Schiff base analogs [RJ-1 a-m] as title compounds. The new compounds were characterized by MP, TLC and representative compounds by 1HNMR, IR, and Mass spectral data

1,4-Diaryl-azetidin-2-ones John W. Clader et al (J. Med. Chem. 1996, 39, 3684-3693) reported a series of azetidinone cholesterol absorption inhibitors related to compound 2(6 in paper). They focused on detailed structure-activity relationship of azetidinone compounds to probe the effect and sensitivity of the nature and pattern of substitution on the hypocholesterolemic activity in 7-day cholesterol-fed hamster model. Investigation identified that 4-alkoxyphenyl and absolute stereochemistry at

Enzyme Inhibition Enzyme inhibitors are substances e.g. A drug, toxin, food which inhibits the action of a certain enzyme by inhibiting or decreasing their biosynthesis. Two types of Enzyme Inhibition: 1. Reversible inhibition Inhibitors bind to enzymes through non-covalent bonds, thus dilution of the enzyme-inhibitor complex results in dissociation of the reversibly bound inhibitor. • Competitive inhibition: The enzyme inhibitor and the substrate competes to bind reversibly to the same site of

Introduction: In this activity each group has a member record their electrical activity of the heart with electrodes. The electrodes will be put on three different locations on the body, the right anterior forearm at the wrist, and on the medial surface of each leg, superior to the ankle. Since the electrodes will not be placed directly over the heart artifacts can result from the recording of unwanted skeletal activity. Therefore the member has to be still, cannot laugh or talk, and when in the

Firstly, due to dynamic exercise, we hypothesised that dynamic exercise will increase heart rate, systolic pressure, pulse pressure, but decreases diastolic pressure due to vasodilation of the aorta, and the mean arterial will remain the same. The figures illustrate the effect of exercise for instance figure 1, 3 ,4, and 5 shows an increase in systolic pressure, pulse pressure, heart rate and mean arterial pressure compared to at rest, whereas figure 2 shows a decrease in diastolic pressure due to

Introduction: The fundamental objective behind the performance of this procedure is to surmise the mechanism of the transfer of genetic material and to accomplish this the model organism Caenorhabditis elegans were implored. The determination of the inheritance pattern of a particular unknown mutant gene in Caenorhabditis elegans was explored. Caenorhabditis elegans was chosen due to the relative ease of maintenance of the organism in laboratory setting, its small size and their short life cycle

Introduction In todays lab we observed the Sow bug and the preferred environment that would most likely be their preferred natural environment. During our observational study we observed a box divided into two chambers. One was filled with wet soil, it was shaded and was non-heated, while the other side of the chamber was dry sand, non-shaded and was heated with a lamp. We ran the experiment three different times, for five minutes with four bugs at a time, while we checked on them every minute to
