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

briefly explain the process of digestion in ruminants Asked by ANUSHA SHISHIR PA... 3 days‚ 1 hour ago Subject:Science 3 Answers The procees of digestion is completedd through four chambers 1)Rumen 2)Reticulam 3)omasumn 4)abomasum In the first two chambers‚ the rume and the reticulum‚ the food is mixed with saliva and separates into layers of solid and liquid material. Solids clump toget her to form the cud or bolus. The cud is then regurgitated and chewed to completely mix it with saliva and

Mastering Concepts 2.1 1. Which chemical elements do organisms require in large amounts? Carbon‚ oxygen‚ hydrogen‚ nitrogen‚ sulfur‚ and phosphorus are the chemical elements that organisms require in large amounts. 2. Where in an atom are protons‚ neutrons‚ and electrons located? An atom’s protons and neutrons are in its nucleus. A cloud of electrons surrounds the nucleus. 3. What does an element’s atomic number indicate? An atom’s atomic number indicates the number of protons in its nucleus

(Prac 1)‚ but this time you will use the enzyme Alkali Phosphatase. These enzymes have different primary (and hence tertiary) structures‚ pH optima and cofactors‚ so are more unlike than alike. However‚ Alkali Phosphatase can also catalyse the hydrolysis of the artificial substrate PNPP to PNP + P i‚ so PNPP will again be the substrate in this prac. The inhibitor you will test will be the yellow-coloured product PNP – so this is an experiment to investigate product inhibition. What do you think
