T. aquaticus is a bacterium that lives in hot springs and hydrothermal vents, and Taq polymerase was identified as an enzyme able to withstand the protein-denaturing conditions (high temperature) required during PCR. Therefore, it replaced the DNA polymerase from E. coli originally used in PCR. Taq's optimum temperature for activity is 75â80 Â°C, with a half-life of greater than 2 hours at 92.5 Â°C, 40 minutes at 95 Â°C and 9 minutes at 97.5 Â°C, and can replicate a 1000 base pair strand of DNA in less than 10 seconds at 72 Â°C.
Glucose and fructose are monosaccharides and are the building blocks of sucrose, a disaccharide. Thus, disaccharides are just a pair of linked sugar molecules. They are formed when two monosaccharides are joined together and a molecule of water is removed -- a dehydration reaction.
Glucose and fructose are simple sugars or monosaccharides. Monosaccharides are the simplest form of carbohydrates and can be combined to form more complex carbohydrates like disaccharides and polysaccharides. Examples of disaccharides and polysaccharides are sucrose (table sugar), lactose (milk sugar) and starch.Most foods contain glucose, fructose or both. Carbohydrates like glucose and fructose are the bodyâs main source of energy.lucose and fructose are naturally found in fresh fruits and vegetables. They are also in fruit and vegetable products made with added sugar because glucose and fructose combine to form common table sugar.
