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 molecule of sucrose. Glucose and fructose are monosaccharide sugars. A monosaccharide is the smallest unit of sugar, mono meaning 1. Sucrose is commonly called table sugar and is a disaccharide. A disaccharide is a sugar that is made up of two sugar units, di meaning 2.Sucrose is produced as glucose and fructose are joined together by a condensation reaction.In the process a water molecule is eliminated. See the following equation.hese sugar molecules include glucose, sucrose, lactose, fructose, maltose, lactose and galactose. Sugar molecules are classified as monosaccharides or disaccharides. The following table lists the common sugar molecules are their chemical formula. Name.
