Biotechnology tools are used in identifying‚ isolating‚ characterizing‚ testing‚ and synthesizing compounds discovered in marine animals and plants and then developed into drugs or other products (Fenical‚ 1993; Davidson‚ 1995; Kobayashi and Ishibashi‚ 1993).

Arene Molybdenum lab Introduction: Organometallic chemistry is the study of chemical compounds that contain carbon atoms bound to a metal atom. Organometallic compounds can contain main group elements‚ or more metallic elements such as zinc or carbon. These compounds tend to have carbon atoms bound to the metal center by σ-bonds. Alternatively‚ transition metals can be involved in the compound‚ which leads to a variety of interesting and diverse chemical characteristics. For example‚ a promising

Antioxidants November 23‚ 2012 Organic chemistry is the study of structure‚ properties and the reactions dealing with carbon compounds (organic chemistry‚ n.d.). This type of chemistry may deal with small items‚ but knowing how organic chemistry works as a whole has an impact on our daily lives and also the occupations some of us consider. Knowing the bases of organic chemistry can be important and sometimes even required to learn for the bases of many health care professions

Para-nitrobenzeneazoresorcinol dye and methyl orange belong to a class of dyes known as “azo colors” which contain the azo group linked to two aromatic nuclei. The nature of the aromatic substituent’s on both sides of the azo group (-N=N-) controls the colors of the azo compound as well as the water- solubility of dyes and how well they bind to a particular fabric. In addition to the azo group‚ the dyes

techniques used to isolate and purify has been by extraction‚ distillation‚ recrystallization‚ and chromatography. In this experiment we will be trying to obtain a pure organic compound from a natural source. Because this natural source it is not only trimyristin and myristic acid that makes it up‚ it’s a mixture of many compounds. Although nutmeg is one of those natural sources that trimyristin is easily extracted from it does take some time to achieve in lab. Ground nutmeg seeds are extracted with methyl
