Ethyl acetate (systematically‚ ethyl ethanoate‚ commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3COOCH2CH3. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues‚ nail polish removers‚ and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. The combined annual production in 1985 of Japan‚ North America‚ and Europe

Case Study Summaries Case 1: J. Wellington Wimpy. Wimpy’s burger meal likely contained simple carbohydrates from the white flour bun‚ sugars in the ketchup‚ and saturated fats from the beef patty and cheese slice. Conversely‚ his turkey sub meal after the transformation likely provided complex carbohydrates from the whole wheat sub roll‚ lower amounts of saturated fats with high amounts of unsaturated fats in the turkey breast slices‚ and unsaturated fats from the veggies. Carbohydrates‚ which

interfere with membrane transport functions. To avoid this the amino groups are converted into urea‚ which is less toxic and can be transported and stored to be released by the excretory system. Urea is the result of two amino groups being joined to a carbonyl (C=O) to form CO(NH2)2‚ the process of which is called the ornithine cycle and takes place in the liver. The ornithine cycle was developed by Hans Krebs in 1932 and is similar to the Krebs cycle through the use of oxaloacetate. One of the steps

CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached

Preparation of food takes a lot of time. Even if the dish is only composed of fruits. A lot of dishes have vegetables in them. These can also be useful especially when preparing lots of different food at the same time. If you look at cooking websites they will suggest to use lemon water. In our experiment we will attempt to find out which is better at preserving the sliced‚ chopped‚ and or diced food. Since our experiments are limited by time and costs‚ we will stick to the simplest of the available
