aldehyde led to the forming Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate. The analyses that were used to prove its composition and structure include; IR spectroscopy‚ thin layer chromatography (TLC)‚ and CHN analysis. A radical copolymerization reaction was conducted‚ with the initiation by radical initiator 1‚1’-azobiscyclohexanecarbonitrile. CHN analysis‚ IR spectroscopy‚ and Proton NMR analysis were used to prove its composition and structure. 1. Introduction The American Chemical Society databases

Synthesis The idea of gender wage discrimination being widely practiced in the United States today is a difficult concept for many to swallow. With the Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964‚ the realization of the existence of the gender wage gap surprises many Americans. These authors bring to the forefront the idea that there is more to the gender wage gap then just companies discriminating against women and minorities. They sight many sources with defined data

Macromolecule is a very large molecule which can get collected in the kidneys. Generally‚ the molecular weight of the macromolecular vehicle is bigger than that of the prodrugs and so this kind of system can achieve the objective. Pro-drugs have the capability to select the goal in the kidney because it can release the active drug by the action of renal enzymes

I. INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group

Galactosemia Galactosemia is an inborn error of metabolism. Because of energy barriers‚ essentially none of the chemical reactions that take place in living things could occur at any measurable rate without the presence of a catalyst. Most catalysts in living things are enzymes that depend on their structure to be able to function. Their structure is determined by their coding on DNA. Inborn errors of metabolism‚ like the one seen in galactosemia‚ are caused by defective genes. Galactosemia

The company that has been chosen for this case study is Jollibee Foods Corporation. Tony Tan Caktiong is the president of Jollibee Foods Corporation. Jollibee began as a two-branch ice cream parlor in 1975 offering hot meals and sandwiches became incorporated in 1978 with seven outlets to explore the possibilities of a hamburger concept and now it becomes one of the fast-food major from the Philippines. The Jollibee mascot was inspired by local and foreign children’s books. Lumba created the product
