Introduction

Chemistry paper outline: Nicotine * I. History and facts * A. Naming and group * a. Solanaceae group of plants classified by it's nicotine which consists of plants such as potatoes, eggplants, tomatoe,etc. * b. most commonly associated with tobacco plants, found when biosynthesis happens * c. Named by the plant Nicotina tabacum * B. Key history * a. 1600's-1700's- Nicotine was introduced to Europe in tobacco and later brought to America, associated with god and later on evil. * b. 1800's-Scientists like Vauquelin and Poselt began studying Nicotine and discovered facts about it such as its weight, formula, structure, etc. * C.1900- Scientists began studying nicotine medical terms as how it can help and damage humans. * d. Many synthesis studies of nicotine occurred. ...read more.

Middle

Enters through absorption into the pulmonary capillary blood flow * b. The half life of nicotine inside is about 2 hours and is spread across human blood. * c. When in acidic environments, it is ionized and can't switch membranes easily, it can penetrate skin as well. * d. When inhaling nicotine it can reach the brain in around 10 seconds making it one of the most addictive forms of taking it. * e. Nicotine in the body is eliminated by metabolizing in liver, lung, and kidney. Excretion depends on pH and flow. * B. Reactions with nicotinic receptors * a. Nicotine acts and increases activity of nicotinic receptors in the nervous system. * b. mimics acetylcholine and depolarizes and opens ion channel. ...read more.

Conclusion

Certain myths about this treatment such as risk of cancer and failure are made but are mostly false. * V. Effects of Nicotine * A. Positive * a. Reduces anxiety, increase cerebral blood flow * b. Regulation of neuronal responses, also used as pain relief but has limitations of toxicities. * c. Also has been documented as an antipsychotic agent * B. Negative * a. withdrawal and acting on reward pathways along with addictive nature * b. Can cause nausea, vomiting and diarrhea. * c. Respiratory distress, hypothermia and has links to circulatory disease due to it spreading across the blood stream. Inhaling is the worst form of taking nicotine. * d. Weight loss also occurs because of loss of appetite and increased metabolism but it can be controlled as a positive outcome as well.

  1. Determination of the formula of Hydrated Iron (II) Sulphate crystals

    Using a powder form would mean that the acid, water and iron sulphate could be placed directly into the volumetric flask and therefore, the loss of Fe2+ ions resulting from the transferral between the mixing container and the volumetric flask would not occur thus improving the accuracy of the results.

  2. Comprehensive and Detailed Chemistry notes

    - Increasing the temperature gives molecules higher kinetic energy to a stage where the activation energy barrier is overcome. - These molecules then collide strongly and more frequently, increasing reaction rate. - Le Chatilier's principle states that since production of ammonia is exothermic, the equilibrium will shift to the left, using up the newly acquired heat.

    This makes them good ammunition for hitting an atomic nucleus hoping it would fuse with it and make the nucleus heavier. The physicist hoped to make heavier new elements than uranium. Nuclear fission reactions differ from radioactive decay, both in a way which the reaction must be started and in the type of products formed.

    bond of a molecule in water, bonding to the alcohol group of serine in the enzyme (Ophardt, 2003). In effect, this blocks the channel of the enzyme preventing arachidonic acid from entering it and producing prostaglandin (Ophardt, 2003). Figure 4 reflects this effect aspirin has on the enzyme.
