Caffeine is a drug commonly used as a central nervous system stimulant. It is found in plants like coffee and tea. Caffeine can also be found in soft drinks‚ and it is regarded as the most widely consumed stimulant drug in the world based on Nehlig‚ Daval‚ & Debry (1992) research. The interaction of caffeine with adenosine receptors in the brains makes an individual more alert. A moderate intake of caffeine results in small healthy risks while high doses could be a catalyst to negative effects like

7. Modelling Polyethylene As mentioned previously‚ PE is one of the most important polymers in the world. ADMET has been used to systematically model commercially relevant polymers‚ specifically PE and copolymers of ethylene and another monomer. ADMET is capable of producing PE with specific sequences of monomer units‚ as well as random copolymers via copolymerization with 1‚9-decadiene. The ability to precisely synthesize these polymers has opened the door to exploring the molecular origins of

and functional groups will be grouped together in alphabetical order. (The prefixes di-‚ tri-‚ etc. are not taken into consideration for grouping alphabetically. For example‚ ethyl comes before dihydroxy or dimethyl‚ as the "e" in "ethyl" precedes the "h" in "dihydroxy" and the "m" in "dimethyl" alphabetically. The "di" is not considered in either case). When both side chains and secondary functional groups are present‚ they should be written mixed together in one group rather than in two separate

mutually exclusive‚ it is not uncommon to find compounds that exhibit only one or the other of the two types. Most geometrical isomers result from cyclic systems or restricted rotation about double bonds. The preparation of fumaric acid by isomerization of maleic acid and addition of molecular bromine to fumaric acid was illustrated in the experiment. Geometric isomers can be interconverted if the double bond is temporarily converted to a single bond‚ about which rotation is relatively

Traditionally‚ symptoms of pain‚ swelling and inflammation were relieved by crudely placing ice cubes on the spot that hurts. Today modern medicine has given us Advil to alleviate common swelling and pain. Advil is the name brand manufacturing of Ibuprofen‚ a non-steroidal anti-inflammatory drug and analgesic. Advil is in the class with other drugs that is listed as “an essential medicine “by the World Health Organization which means that it is needed for basic health‚ is safe and cost effective

EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for
