tom hanks essays

tom hanks essays From a stressful childhood to a successful career, Tom Hanks has mastered every angle of film making. While discovering drama in high school, Hanks chose acting as his career choice in college upon seeing The Iceman Cometh. After years of hard work and dedication, Hanks made it to the big screen where he has progressed ever since. Still continuing to act, Tom Hanks has been producing, directing, and writing screen plays. Born on July 9, 1956, in Concord, California, Thomas J. Hanks was the son of Amos and Janet Hanks. His Parents split up when he was five, and the three oldest kids (Hanks was the third) went with their father, Amos, a chef by trade who uprooted the family about every six months chasing after a job (Tom Hanks). His father married two more times after divorcing Toms mother. Eventually, in 1966, they settled down in Oakland California when Tom was ten. During that nomadic period of five years Hanks attended six different grammar schools. Tom finally found a home at his high school, Skyline High, where he was big on athletics. It was also during high school that he discovered acting. It was when Tom watched a friend perform in the schools production of Dracula that he first considered acting. Shortly after attending the schools production, Tom joined the Thespian Club and worked as a stage manager for the schools production of My Fair Lady. Later he won roles in Night of the Iguana, Twelfth Night, and South Pacific. As a senior year Hanks was honored with Skylines highest acting award, Best Actor. This was given to him just 20 years before he would receive his first Oscar. From 1974 to 1976 Tom Hanks attended Chabot College in Hayward, California. There he took one drama class per quarter. To fulfill a course requirement, Tom saw the Berkeley Repertory Production of The Iceman Cometh. The performance of Joe Spano as Rocky in the play fired a d...

Cholesterol - Assignment Example Cholesterol bromination can be used to purify cholesterol (Barton, Miller & Young 98). In most cases, oxidation refers to the addition of the oxygen atom to a substance. However, in organic chemistry, oxidation refers to the loss of bond by carbon atom to hydrogen forming new bonds with other atoms. The overall reaction is characterized by loss of electron density hence loss of the electron. Cholesterol is capable of undergoing both autoxidation and photo-oxidation to produce oxysterols in each case. The common oxidants used for cholesterol oxidation are zinc and sodium dichromate. The first step involves the formation of the ketone, where the O double bond replaces the OH functional group. Then zinc is used to remove the bromine atoms (Stewart, Lee & Can 439). Debromination is the opposite of the bromination because it involves the removal of the bromine atoms from the organic molecule. It is one of the dehydrogenation reactions where cholesterol dibromide is boiled in the presence of alcoholic halide to produce the corresponding alkene molecule. The chemistry behind this reaction is that the bromine attached to the carbon in the alkyl bromide undergoes a reaction with hydrogen that is attached to the ÃŽ ²-carbon that releases the hydrogen bromide. The product of the reaction is the formation of a double bond between ÃŽ ± and ÃŽ ² carbon resulting into an alkene (House & Row 182). Isomerization is a process involving the transformation of a molecule into another with the same atoms but different arrangement. The new molecule is called an isomer. In the case of cholesterol, oxalic acid assists in shifting 5-Cholesten-3-one to a 4-Cholesten-3-one by shuffling of the position of the carbon-carbon double bonds. Oxalic acid provides the acidic medium that favors shifting and formation of a double bond to a new location leading to the formation of the conjugated system with the ketone group (Seager, Spencer & Slabaugh 123). Crystallization is the
