Recently‚ by adding bulky ligands in replacement of the two amines on trans-platin‚ antitumor activity has been found‚ and even activity on cis-platin resistant tumors‚ suggesting that anticancer mechanism is not limited to lesion causing 1‚2 intrastrand

First‚ the synthesis of the coordination compound‚ KaFeb(ox)cdH2O‚ needed to be carried out. This was achieved by weighing out 8.29 grams of K2C2O4 with a Dial-a-gram balance. Once measured‚ the 8.29 grams K2C2O4 were placed in a 125 mL Erlenmeyer flask. 25 mL of deionized water were then added to the 125 mL flask and stirred with the K2C2O4 until complete dissolution was achieved. Next‚ 4.11 grams of FeCl3 were weighed out using the balance previously mentioned. Once the 4.11 grams were measured

This provided the mass of 1.6 grams which was found by subtracting the mass of the Erlenmeyer flask‚ aluminum cover‚ and rubber band from the mass of the Erlenmeyer flask‚ aluminum cover and rubber band and unknown gas after heating. Then the temperature of the gas was determined by taking the temperature of the hot water which was 94 and converting it to Kelvin by adding 273.15. This

The first experiment focused on the reaction between alkaline luminol H2O2‚ the most common luminol solution‚ and cysteine‚ one of the twenty essential amino acids. In this experiment‚ 105 g=mL cysteine solution‚ 2.0 105 mol=L Cu(II) solution‚ and the mixture of 1.0 105 g=mL cysteine with 2.0 105 mol=L Cu(II) were tested. However‚ no

Introduction: In this experiment‚ when vinyl strip and acetate strip is rubbed by tissue‚ it will charge the vinyl strip negatively and acetate strip positively caused by the transfer of electron between the strip and tissue. If molecules have non zero bond dipole‚ because polar molecule must have a non-zero molecular dipole where electron spend more of their time closer to one atomic nucleus than the other and make one end partially positive or negative than the other end. Different charge will

This is a silver solid that can be easily formed‚ machined‚ or cast. In this lab‚ we will be finding the limiting reactant between Copper(II) Chloride and Aluminum. The limiting reactant is‚ reactant is‚ the reactant in a chemical reactant that limit’s the amount of the product that can be formed. We will also need to find the molarity

A spectrophotometer evaluated the measurement of color change over a period time due to product being formed. Determining unknown phosphatase and effects from different inhibitors were determined by varying the pH and substrate concentrations. The unknown phosphatase analyzed showed it was an acidic phosphatase. Ph 5 had the most enzyme activity and pH 9 presented 1/3 of enzyme activity‚ while pH of 11 had

characteristic properties of slime can be explained by polymerisation reactions. Polymers can be explained most simply by the polymerisation of the molecule ethylene into polyethylene (see figure 1 below). Figure 1. Polymerisation of polyethylene from ethylene. In this example‚ the double bond between the carbon atoms is broken‚ allowing each carbon atom to form one more bond between another molecule. The double bond between the carbon atoms is weaker because the type of orbital is ‚ compared

Determining Allele Frequencies of the PV92 Alu Element using DNA Isolated from Human Cheek Cells and PCR Amplification Background Alu elements are the most abundant repetitive elements in the human genome that have mobilized throughout primate genomes by retrotransposition over the past 65 million years ago from a 5’ to 3’ fusion of the 7SL RNA gene‚ to reach the present number of more than one million copies. Over the last few years‚ several lines of evidence demonstrated that these elements
