various building blocks can be controlled using the fundamentals of reticular chemistry. This offers a great potential for tailoring MOFs properties for a wide scope of high-tech applications (high-capacity adsorbents‚ membranes‚ thin film devices‚ catalysis‚ biomedical imaging‚ etc.). MOFs have traditionally been used for gas storage and separation‚ and much less attention has been devoted to their electronic properties3. This has changed in the past decade and MOFS with high electrical conductivity

Cofactors‚ mostly metal ions or coenzymes‚ are inorganic and organic chemicals that assist enzymes during the catalysis of reactions. In the performed experiment the cofactor used was Magnesium in the form of Magnesium sulfate (MgSO4). Two replicates were prepared‚ one with the cofactor and the one without. Since respiration produces carbon dioxide‚ the rate of cellular

Alkanes The reaction between alkanes and fluorine This reaction is explosive even in the cold and dark‚ and you tend to get carbon and hydrogen fluoride produced. It is of no particular interest. For example: The reaction between alkanes and iodine Iodine doesn’t react with the alkanes to any extent - at least‚ under normal lab conditions. The reactions between alkanes and chlorine or bromine There is no reaction in the dark. In the presence of a flame‚ the reactions are

DNA REPLICATION WHAT IS DNA? DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A)‚ Guanine (G)‚ Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose. THE PROCESS OF DNA REPLICATION How DNA replicates is quite a simple process. First‚ a DNA molecule is "unzipped". In other words‚ it

body of potentially harmful toxins in order to make them more water-soluble. They do this by inserting one atom of molecular dioxygen into an organic substrate (RH) while the second oxygen atom is reduced to water (RH+02 + 2e- → ROH + H20). CYP catalysis substrate binding to the heme site requires a two-electron transfer with NADH-cytochrome P450 oxidoreductase (CPR) to the highly reactive iron-oxo intermediate which promotes oxidation and returns the P450 to a resting state. Most CYP’s can bypass

HISTORICAL BACKGROUND In 1878 kuhne used the word enzyme (Greek: in yeast) to indicate the catalysis taking place in biological systems. Isolation of enzyme system from cell free extract of yeast was achieved in 1883 by Buchner. He named the active principle as Zymase (later found to contain a mixture of enzymes)‚ which could convert sugar to alcohol
