millions of times. The shape of an enzyme creates a phenomenon in which only select particles can enter the active site. For example‚ the enzyme amylase is only able to break down starch polymers. Changing the shape of an enzyme renders it useless. In this experiment‚ every group but the Popbeads group conducted a hydrolysis reaction. The Popbeads represented a condensation reaction. This is because every group but the Popbeads simulated a polymer (toothpick) being broken down. The Popbeads polymers

acidic medium and oxidative stress. An ideal stability indicating method is one that quantifies the standard drug alone and also resolves its degradation products. So described‚ different types of stress were used thermal‚ oxidation‚base hydrolysis and acid hydrolysis. Although unknown degradant peaks were observed in the acid‚ base‚ peroxide and thermal study‚ no degradant peaks were reported in the retention time(Rt) of lamivudine‚ zidovudine and nevirapine. Therefore‚ lamivudine‚ zidovudine and nevirapine

first. To find the solubility of the fats‚ oils‚ soaps‚ and detergents‚ each of them were placed into different solvents to see if they dissolved. None of the oils and fats were soluble in water (H2O)‚ sodium hydroxide (NaOH)‚ or hydrochloric acid (HCl)‚ but they were soluble in toluene and partly soluble in acetone. Testing the soaps and detergents for their solubility in water is the most important solubility test because they should form a lather that allows them to clean easily. Most of the soaps

How Carboxylic Acids and Alcohols React to Produce Esters: Esters and Ester Production: Esters are abundant and ever present‚ and are the chemical basis of almost all fatty acids and oils. Small esters are responsible for the aroma of fruits‚ perfumes and‚ by extension‚ wines and other alcohols. Esters are formed when a carboxylic acid and an alcohol chemically combine‚ losing a molecule of water in the process. Carboxylic acids are organic molecular compounds that form a homologous series
