Information: - The Flag Football World Championship was created in 2002 in Cancun , Mexico , with six countries . In its 11th annual event , the 2010 World Cup of Flag Football Festival took place in Boston in July . In 2001 , the championships were held in Toronto , Canada , and played host to eight countries . The winner was Australia 's team the '' Roo Boys '' captained by Brendan Neighbour . The 2014 tournament will be held in Jerusalem , Israel . - Canadian football is a form of gridiron football played in Canada in which two teams of 12 players each compete for territorial control of a field of play long and wide attempting to advance a pointed prolate spheroid ball into the opposing team's scoring area (end zone). - Boston (pronounced ) is the capital and most populous city of the Commonwealth of Massachusetts in the United States. Boston is also the seat of Suffolk County, although the county government was disbanded on July 1, 1999. The city proper covers with an estimated population of 667,137 in 2015, making it the largest city in New England and the 23rd most populous city in the United States. The city is the economic and cultural anchor of a substantially larger metropolitan area known as Greater Boston, a Metropolitan Statistical Area (MSA) home to a census-estimated 4.7million people in 2014 and ranking as the tenth-largest such area in the country. Alternately, as a Combined Statistical Area (CSA), this wider commuting region is home to some 8.1million people, making it the sixth-largest as such in the United States. - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. - Flag football is a version of US-American football or Canadian football where the basic rules of the game are similar to those of the mainstream game (often called "tackle football" for contrast), but instead of tackling players to the ground, the defensive team must remove a flag or flag belt from the ball carrier ("deflagging") to end a down.

Information: - A lipase is any enzyme that catalyzes the hydrolysis of fats (lipids). Lipases are a subclass of the esterases. - In biology, lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries as well as in nanotechnology. - Enzymes are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process upon which enzymes may act are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. The set of enzymes made in a cell determines which metabolic pathways occur in that cell. The study of enzymes is called "enzymology". - Fat is one of the three main macronutrients, along with carbohydrate and protein. Fats, also known as triglycerides, are esters of three fatty acid chains and the alcohol glycerol. - Hydrolysis usually means the cleavage of chemical bonds by the addition of water. When a carbohydrate is broken into its component sugar molecules by hydrolysis (e.g. sucrose being broken down into glucose and fructose), this is termed saccharification. Generally, hydrolysis or saccharification is a step in the degradation of a substance. - In chemistry, esters are chemical compounds derived from an acid (organic or inorganic) in which at least one OH (hydroxyl) group is replaced by an Oalkyl (alkoxy) group. Usually, esters are derived from a carboxylic acid and an alcohol. Glycerides, which are fatty acid esters of glycerol, are important esters in biology, being one of the main classes of lipids, and making up the bulk of animal fats and vegetable oils. Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Phosphoesters form the backbone of DNA molecules. Nitrate esters, such as nitroglycerin, are known for their explosive properties, while polyesters are important plastics, with monomers linked by ester moieties. - An esterase is a hydrolase enzyme that splits esters into an acid and an alcohol in a chemical reaction with water called hydrolysis. - Triglyceride lipases are lipases that hydrolyse ester linkages of triglycerides . These lipases are widely distributed in animals , plants and prokaryotes . This family was also called class 3 lipases as they are only distantly related to other lipase families .
