Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase. The mobile phase was a nonpolar solvent composed of ethanol

It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided.

Rational for Choosing the Eizayaga Layers Method Dr Eizayaga‚ an Argentinean homeopath‚ developed a method to treat chronic cases (Watson 2004). He believed that patients have separate levels of disease‚ which need separate prescriptions. In most chronic cases‚ there will have been long-term use of drugs to suppress the specific pathology and symptoms (Kramer 2006). This means that the true picture of the disease may be obscured and toxicity in the system could also be causing side effects

ozone layer or ozonosphere‚ region of the stratosphere containing relatively high concentrations of ozone‚ located at altitudes of 12-30 mi (19-48 km) above the earth’s surface. Ozone in the ozone layer is formed by the action of solar ultraviolet light on oxygen. The ozone layer prevents most ultraviolet (UV) and other high-energy radiation from penetrating to the earth’s surface but does allow through sufficient ultraviolet rays to support the activation of vitamin D in humans.

in Hong Kong The ozone layer present in the stratosphere of the Earth is utmost important to us as it protects us from the exposure of ultraviolet rays which leads to several harmful effects. Without the ozone layer‚ human will be more prone to skin cancer and eye cataracts. Ultraviolet rays can also cause harm to marine life by reducing the amount of planktons and consequently depreciates the amount of fishes in the ocean. Besides that‚ the depletion of the ozone layer disrupts the production of
