True Potential In an age of distant past‚ darkness would sweep door to door every sunset. Seeking a solution‚ Thomas Edison made his greatest contribution to civilization - the incandescent light bulb. Formulating over 1000 inventions‚ the renowned inventor once uttered the following words‚ “If we all did the things we are capable of‚ we would literally astound ourselves” (BrainyQuote). One understands that the late inventor is insinuating that human potential is unbounded. Edison’s accomplishments

presence of starch and a red-brown in the presence of glycogen. A negative outcome results in no colour change and all solutions remain a very pale yellow (Pavia‚ 2005). Benedict ’s solution was used to identify the presence of reducing sugars; the aldehyde functional group is the part that reacts in the test. A positive indicator of the test is the formation of a coloured precipitate of the blue solution‚ ranging from yellow-green to red-brown (Hequet and Abidi‚ 2006).

Introducton : The most common macromolecules found in living organisms are carbohydrates ‚ lipids‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain tests to determine the presence of

Elisa Hofmeister Kokesh Hour 3 AP Chemistry 5-29-12 The Chemistry of Coffee Green Coffee- Before coffee is roasted‚ it is referred to as “green coffee”. The green coffee is primarily made up of caffeine‚ lipids‚ carbohydrates‚ proteins (amino acids)‚ and organic acids (although inorganic acids exist in coffee as well). These groups are quite stable in the green phase‚ and it is the carbohydrates‚ proteins‚ and acids that will undergo significant reactions during roasting to produce coffee

However‚ these are not the concern for the food technologist. Autoxidation (atmospheric oxidation) under the mild processing and storage conditions of the food industry is of utmost importance due to the resultant malodor- and malflavor-producing aldehydes and ketones. The oxidation of the highly unsaturated fats resulting in polymeric end products and
