Reginald Alfred "Reggie" Bush II (born March 2, 1985) is an American football player for the Detroit Lions of the National Football League (NFL). He plays the position of running back.
Bush played football at Helix High School in La Mesa, California, then played football at the University of Southern California. Bush won the 2005 Heisman Trophy, which is for the best player in college football, but in 2010, he gave the award back because of claims that he took gifts while in college that would have made him a professional athlete while still in college.
The New Orleans Saints chose Bush with the second pick in the 2006 NFL Draft. In 2010, Bush won a Super Bowl with the Saints over the Indianapolis Colts.
Globular protein
A globular protein is one of a common type of protein.
They are one of three types of protein. The others are fibrous and membrane proteins.
Their structure is a result of protein folding. They are made of polypeptide chains folded into a compact sphere shape.
They are soluble in water because of the hydrophilic ('water-loving') side chains that project from the outside of the molecules. They play an important role in metabolic reactions.
Unlike proteins which only have a structural function, globular proteins can act as:
Globular proteins include myoglobin and hemoglobin.
Globulins are all globular proteins except albumins. They have higher molecular weights than albumins. They are insoluble in pure water but dissolve in dilute salt solutions.
Some globulins have important function as antibodies, others are responsible for the transport of lipids, iron or copper in the blood.
David Haye
David Haye is a British boxer. He is the WBA heavyweight champion and is nicknamed "The Hayemaker". He is 1.91 metres (6 feet 3 inches) tall. Before he became a heavyweight, he boxed in the cruiserweight division, where he held all the major titles. His most famous cruiserweight fights were against Jean-Marc Mormeck and Enzo Maccarinell. He has lost only once in his career.
Haye moved up to the heavyweight division and beat Monte Barrett in 2008. In October 2009, he beat Nikolai Valuev, who is 7 feet tall, to become the WBA champion. In 2010, he beat John Ruiz. He defended his title against fellow Briton Audley Harrison in November 2010.
Haye started his career as an amateur. He reached the finals of the 2001 world amateur championship in the heavyweight class, where he lost to Odlanier Solis. He turned professional in the cruiserweight division in December 2002. His first professional fight was meant to be against Valeri Semishkur, but Semishkur pulled out. Instead, Haye fought and beat Tony Booth on 8 December 2002. He had seven fights in 2003, and won all of them. He won his tenth fight in a row when he beat Arthur Williams on 12 May 2004. He won those ten fights with a total of only 20 rounds. In his match against IBO champion Carl Thompson on 10 September 2004, he lost for the first time in his career. In his next match, on 10 December 2004, he beat Semishkur in the first round.
Haye won the European title on 16 December 2006 when he beat Alexander Gurov. He won the match after only 45 seconds. On 24 March 2007, in his first match as European champion, he beat Lasse Johansen. On 27 April 2007, he had his first heavyweight fight, against Tomasz Bonin. Haye won in the first round. Shortly after the fight, Haye said he had plans to move up to the heavyweight division. "I'm absolutely certain I can rule the heavyweight roost", he said. On 10 November 2007, he beat Jean-Marc Mormeck to win the WBA, WBC, and "Ring" magazine titles. Haye was knocked down in the fourth round, but hit Mormeck with a series of blows in the seventh to win by technical knockout. He became the UK's sixth boxing champion. On 8 March 2008, he beat Enzo Maccarinelli to win the WBO title. Haye hit Maccarinelli with two big punches before the referee stopped the match. Haye said he planned to move up to the heavyweight division. A few weeks after the fight, Wladimir Klitschko, the IBF, IBO, and WBO heavyweight champion, said he wanted to fight Haye.
Haye gave away his titles at cruiserweight and moved up to the heavyweight division. He beat Monte Barrett on 15 November 2008, winning in the fifth round. Before the fight, he said fighting Barrett was a big risk and that he might have retired if he lost. He was meant to fight Wladimir on 20 June 2009, but pulled out. On 31 October 2009, he beat Nikolai Valuev, who is 7 feet tall, to become the WBA champion. Haye was 98 pounds lighter than Valuev; before this fight, no-one had won a heavyweight title match weighing this much less than their opponent. Haye said he has wanted to be the heavyweight champion since he was a toddler. He then beat John Ruiz on 3 April 2010 and Audley Harrison on 13 November 2010. He now says he wants to fight Wladimir or his brother Vitali, who holds the WBC belt. The two brothers are regarded as the best heavyweights in the world. Haye says he plans to retire before his 31st birthday.
Haye was born on 13 October 1980 in Bermondsey, London. He went to Snowsfield primary school and Bacon's College. Jade Goody, winner of the television show "Big Brother", was in his class. Haye is married and has a son called Cassius, named after Cassius Clay, the birth name of Muhammad Ali. His training camp is based in Kyrenia, Northern Cyprus. He started training there in 2007 and sometimes fights with the Northern Cyprus flag on his shorts. He supports the football team Millwall. In September 2010, a newspaper in Northern Cyprus said Haye had become a citizen of Northern Cyprus.
Xanthan gum
Xanthan gum is a polysaccharide (a complex form of sugar). It is added to certain foods, such as salad dressings, to make them thicker. It is also added to cosmetics to keep the ingredients from separating. To make xanthan gum, workers deliberately add a kind of bacterium, "Xanthomonas campestris", to glucose or sucrose. They let the mixture ferment for a while, and then add isopropyl alcohol to separate the polysaccharide from the mixture. They dry the polysaccharide, grind it into a powder, then add it to a liquid. The xanthan gum is then ready to use.
Allene Rosalind Jeanes and her research team at the United States Department of Agriculture first discovered xanthan gum. The team was studying many biopolymers to see whether some of them were useful, and how they could be used. The Kelco Company was the first company to produce xanthan gum in the early 1960s. At that time, Kelco called xanthan gum by its brand name, Kelzan. Later, in 1968, xanthan gum was tested and declared safe to be used in food. The USA, Canada, Europe, and many other regions and countries now accept xanthan gum as a safe food additive.
Xanthan gum is a very effective thickener. It is stable under a wide range of temperatures and pH. Only 0.5% of xanthan gum is added to most foods to thicken them. The thickening property of xanthan gum decreases when a food is mixed, shaken or chewed, but it thickens up again when the force is removed. This property is called pseudoplasticity. Sometimes this property can be very useful. For instance, the xanthan gum added to salad dressing makes the dressing thick enough to cling to a salad, but shaking the bottle of dressing makes it temporarily thin and easier to pour.
Salad dressings and sauces contain xanthan gum. Even though xanthan gum is not an emulsifier, it helps to keep an emulsion stable so that the oil in it does not separate. Xanthan gum also helps to keep spices and other solid bits of food evenly distributed in a liquid. Xanthan gum, guar gum and locust bean gum help to give ice cream and other frozen foods a creamy texture. Gluten-free bakers use xanthan gum instead of gluten to make bread dough or batter "sticky." Packaged egg whites or egg substitutes contain xanthan gum to replace the fat and emulsifiers found in egg yolks.
