    questions that are rarely touched by economic theorists despite their obvious importance for our understanding of economic processes in the world. No fully formalized model will be proposed here. Instead, the focus will be on interaction between economic elements and emergence of structures. These ideas have been successfully elaborated in natural science by physicists. That is why it makes sense to look for some analogies between physical and economic concepts, and then to find ways of employing principles

    Copper Sulfate Research Paper

    crushed so easily, or why water has such a low melting point? This is due to the chemical properties of the materials and what they are made of! Everything in the world is made up of atoms. Atoms are the smallest forms of matter. What makes materials the way they are, is the bonds between the atoms in the materials. Every atom contains a nucleus which holds protons and neutrons, with electrons around the outside. Protons are positively charged, electrons are negatively charged

    Structure and Function The word protein was first coined in 1838 to emphasize the importance of this class of molecules. The word is derived from the Greek word proteios which means "of the first rank". This chapter will provide a brief background into the structure of proteins and how this structure can determine the function and activity of proteins. It is not intended to substitute for the more detailed information provided in a biochemistry or cell biology course. Proteins are the major

    Give an Account of the Molecular Structure of Carbohydrates. (10)

    carbohydrates. (10) Adam Muscat Carbohydrates contain 3 elements: Hydrogen, Carbon and Oxygen. They can be split into 3 different catagories: Monosaccharides which include glucose, fructose and galactose. Thses can be triol (3 carbons) pentol (5 carbons) or hexol (6 carbons). The most common hexol is glucose. An alpha glucose molecule has a ring structure. The difference between alpha glucose and beta glucose is that on the first carbon atom the OH and H are reversed. Diaccharides are formed by

    Chemical Conversion Processes

    solvolysis often refers to an organic chemistry context, hydrolysis is very common in inorganic chemistry, where aqua complexes of metal ions react with solvent molecules due to the Lewis acidity of the metal center. For example, aqueous solutions of aluminium chloride are acidic due to the aqua-aluminium complex losing protons to water molecules, giving hydronium ions which lowers the pH. In organic chemistry, hydrolysis reactions often give two fragments from an initial substrate. For example, the hydrolysis
