Introduction: Hurler Syndrome (MPS-I)‚ otherwise classified as Mucopolysaccharidosis‚ is the most severe form of this disease and is caused by cells being unable to break down dermatan sulfate and heparan sulfate during regular metabolism(Laberge‚ 2010). The build up of these two by-products disturbs regular cell functionality and this may cause damage within the tissues of organs (Laberge‚ 2010). Two major symptoms found within an individual with Hurler Syndrome are skeletal deformities and

ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms. It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi)‚ and needs energy. The overall reaction sequence is: ADP + Pi → ATP‚ where ADP and Pi are joined together by ATPsynthase Energy is often released in the form of protium or H+‚ moving down an electrochemical

TOPIC 2 Metals The History of Metals * Uses of metals through history: * Copper Age (3200-2300 BCE) – copper and tin were most common metals‚ and were used for ornaments‚ weapons and tools. * Bronze Age (2300-700 BCE) – copper‚ tin and bronze were used for tools‚ weapons and transport. They produced bronze by heating copper and tin with charcoal. * Iron Age (1000 BCE – 1 CE) – iron steel and lead was used for tools‚ weapons and pipes. Iron is much harder than bronze.

Figure 1 shows the structure of 2MBI‚ 2MBI-Au‚ 2MBI-Pd and 2MBI-Ni before and after structure optimization. The drawn 2MBI is presented in Figure 2a and the optimized structure of 2MBI is illustrated in Figure 2b. The most important lengths and angles of bonds for the optimized structure of 2MBI are reported in Table 1. In the optimized structure of 2MBI component‚ S-H‚ S-C‚ C-N bond lengths and the HSC‚ SCN‚ CNH‚ SCN(H) bond angles were 1.386A°‚ 1.667A°‚ 1.377A°‚ 93.291°‚ 125.921°‚ 126.521°‚ 120

each of these compounds will be present in the final product. Both TLC and CG are excellent methods of measuring the presence of a given substance. Both methods turn around a compounds polarity. As one recalls‚ polarity is a measure of the electronegativity of a compound determined by their placement in the periodic chart. Specifically‚ in this lab we are talking about the difference in polarity between the atoms of oxygen and carbon. Ferrocene is relatively low to none in polarity. Acetylferrocene
