Galactose

energy sources for the body because it can be easily converted into glucose, which is required to carry out basic tasks or respiration. The basic building blocks of carbohydrates are monosaccharaides and these are sugars like glucose, fructose and galactose. These are ideal energy sources

rate of respiration in Experiment A. 10mL of yeast suspension was placed into each of the 7 large diameter test tubes. Then after that was completed, six of the seven tubes were filled with a different type of sugar: glucose, fructose, lactose, galactose, sucrose, honey, and the 7th tube were filled with water for the control of this experiment. The tubes were filled approximately ¼ inch below the rim of the tube according to the lab book. After this procedure was completed, all the seven tubes were

mammal milk, which includes lactose intolerance, a multitude of substitutions for milk containing lactose have been promoted to lactose intolerant individuals. Lactase is an enzyme that catalyzes the reaction of lactose hydrolyzing into glucose and galactose, which allows it to be digested. Humans naturally produce this enzyme, however, for some this production ceases as they age. Given that humans cannot digest lactose if it is not properly broken down, many intestinal issues can occur, such as bloating

through the gel, which separates the molecules based on size. Smaller and highly negative molecules travel faster through the gel than larger and highly positive molecules. Agarose is a polysaccharide, containing the two sugars D-galactose and 3,6-anhydro-L-galactose, and is derived from the seaweed. The DNA sample is cleaved into small pieces by restrictive enzymes. Agarose gel electrophoresis can be broken down into three stages: gel preparation, loading the gel, and running to gel. First, agarose

agaribose, which comprises the alternating units of the galactose and 3,6-anhydro galactose. It is approximately at the concentration between 1-3%. Agarose gels are prepared from suspending the dry agarose in the aqueous buffer, then boiling the mixture until a clear solution is formed. This is poured and allowed to cool down to room temperature to form a rigid gel. Agarose gel is formed by the polymerization of D-galactose and 3,6- anhydro –L-galactose. It is

Question #4 (2 Points) What is genomics? Genomics is the study of similarities and differences in genomes between living organisms, either between or within species, using experimental methods derived from the acquisition of entire genomes due to quicker and cost effect sequencing. There are two approaches to studying genomics comparative and functional genomics. Comparative genomics gives insight to the function of genes by comparing sequences to each other. This process can be done on single

concertation, since fructose can be directly incorporated into the glycolysis reaction. Fructose is a monosaccharide, so it doesn’t utilize energy to hydrolysis a reaction. On the other hand, galactose is a disaccharide which requires energy in order to be hydrolysis into a monosaccharides. The hydrolysis of galactose to a monosaccharide is tends to be a slow reaction. According to another experiment, yeast tends to metabolize fructose faster than

carbohydrates. Examples of monosaccharides include glucose, fructose, and galactose. These sugars are combined to form disaccharides, or two sugars. Disaccharides form when two monosaccharides bind using the process of dehydration synthesis. Examples of disaccharides are sucrose, maltose, and lactose. The monomers of sucrose are glucose and fructose. The monomers of maltose are glucose and glucose. The monomers of lactose are galactose and fructose. The binding of multiple monosaccharides and disaccharides

will not be found in the solution because it will not have been broken down. This statement can be affirmed because milk is made out of the two monosaccharides glucose and galactose that yield lactose through a reaction known as dehydration synthesis. Dehydration synthesis reactions occur when two molecules like glucose and galactose both have OH_ and H+ atoms on the ends of their molecular rings. The attraction causes the OH_ to pull the proton H+ off of its molecule to form H2O, while a single oxygen

Abstract This experiment is to study and measure the enzyme activity of β-galactosidase in the different concentrations of o-Nitrophenylgalactoside (ONPG) using a spectrophotometer. The spectrophotometer was also set at 420nm, a wavelength which is best for recording the absorbance values for the experiment. From the results, 0.9mM ONPG solution has the highest absorbance and 0.1mM ONPG solution has the least. Also, 0.5mM ONPG solution has the highest rate of enzyme activity and it is the most efficient
