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.
A fructooligosaccharide (also written fructo-oligosaccharide) is a carbohydrate, which is made out of a short chain of fructose molecules.It is also classed as an oligosaccharide; oligo meaning few and saccharide, sugar. Fructooligosaccharides are also sometimes called oligofructose.Often the term is abbreviated to the letters FOS. Together with inulin fiber, fructooligosaccharides are probably most recognized for their prebiotic qualities.ou will also find that fructo-oligosaccharide or oligofructose, as it is also known, is added to many processed foods, mainly as a prebiotic or fiber supplement but also as a sweetener. This type of FOS is not natural.
