Dehydrating Cyclohexanol • Introduction The purpose of the lab experiment is to prepare cyclohexene from cyclohexanol through an acid-catalyzed dehydration. In order to produce the cyclohexene from cyclohexanol‚ an elimination reaction was performed. First by protonating the oxygen of the alcohol and creating an oxonium ion we replaced the poor leaving group (OH) into a better leaving group (OH2+). Second‚ dehydrating the cyclohexanol using phosphoric acid and sulfuric acid as acid catalysts

What Type of Bread Molds the Fastest? Bread has been part of the human diet for thousands of years. Generally‚ breads were prepared and baked daily for consumption. Today’s bread contains preservatives to make it last longer in the home. This project is about discovering what type of bread molds the fastest out of white‚ wheat‚ rye‚ and homemade. To do this experiment a total of four types of bread were observed in the same environment. A photo of each slice of bread was taken every other day. A

Parkinson’s disease is caused due to the production of insufficient dopamine synthesis in brain….. Degradation of catecholamines The catecholamine is inactivated by oxidative deamination by monoamine Oxidase (MAO) and by o-methylation carried out by catechol-o-methyl-transferase (COMT) as the one-carbon donor. -Two reactions can occur in either direction -the aldehyde products
