The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient

Plants‚ also called green plants (Viridiplantae in Latin)‚ are living organisms of the kingdom Plantae including such multicellular groups as flowering plants‚ conifers‚ ferns and mosses‚ as well as‚ depending on definition‚ the green algae‚ but not red or brown seaweeds like kelp‚ nor fungi or bacteria. Green plants have cell walls with cellulose and characteristically obtain most of their energy from sunlight via photosynthesis using chlorophyll contained in chloroplasts‚ which gives them their

was awarded jointly to Leland H. Hartwell‚ Tim Hunt and Sir Paul M. Nurse "for their discoveries of key regulators of the cell cycle". They have identified key molecules that regulate the cell cycle in all eukaryotic organisms‚ including yeasts‚ plants‚ animals and human. These fundamental discoveries have a great impact on all aspects of cell growth. Defects in cell cycle control may lead to the type of chromosome alterations seen in cancer cells. This may in the long-term open new possibilities

Separation of Mixtures 9/11/11 * Introduction: A compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Unlike a compound‚ a mixture is a material system made up by two or more different substances which are mixed together but are not combined chemically. There are two kinds of mixtures‚ homogeneous and heterogeneous. Homogeneous mixtures have the same composition and appearance throughout
