Water = not a saccharide Glucose = monosaccharide Fructose = monosaccharide Galactose = monosaccharide Sucrose = disaccharide Lactose = disaccharide Starch = polysaccharide Honey = primarily monosaccharides with some disaccharide Saccharine = not a saccharide Nutrasweet = not a saccharide

components of the walls that surround plant cells. * The carbohydrates (saccharides/sugars) are divided into four chemical groups: monosaccharide‚ disaccharides‚ oligosaccharides and polysaccharides. * Monosaccharides include Glucose‚ Fructose‚ and Galactose etc. * Disaccharides include Sucrose‚ Maltose‚ and Lactose etc. * Polysaccharides include Starch‚ Glycogen‚ Cellulose and Chitin. * Aldehydes (–CHO) and ketones (= CO) are active groups or functional groups in carbohydrates

Place beaker on scales and zero the scales 2. Measure 5g of fructose by placing it in the beaker 3. Take beaker off the scales and add 100mL of distilled water and stir for 30seconds to form a sugar solution 4. Measure 5g of yeast powder in the plastic container on the scales 5. Add the yeast to the sugar solution

Compare the Rate of Carbon Dioxide Production by Yeast under Anaerobic Conditions using different Carbohydrate Substrates. Hypothesis. The hypothesis that I draw is that "" out the five carbohydrate substrates that I will use‚ Glucose will produce the highest volume of Carbon Dioxide at every five-minute interval. Null Hypothesis. The null hypothesis that I am composing is that "" the five carbohydrate substrates that I am to use will not produce any Carbon Dioxide. Scientific Research. Under

(Wolfe‚ 2000) Importance of Aldolase B Enzyme -Glucose and fructose are the components that make up sugar (sucrose). -In order to make ATP (energy)‚ glucose and fructose need to go through glycolysis and enter the Krebs cycle. -Fructose needs enzymes to break it down further‚ before it can enter the glycolysis process. -Initially‚ fructose is broken down by the enzyme fructokinase into fructose-1-phosphate. -The substrate fructose-1-phosphate (F-1-P) is then further broken down by an enzyme

Second‚ the sugar breaks down into fructose and glucose. Third‚ fructose and glucose decompose into smaller particles. They allow people to smell the sugar because they become more volatile. Fourth‚ fructose and glucose oligomerization‚ which is a process of combining the fructose and glucose molecules and forming di-D-fructose Dianhydride‚ happens. Fifth‚ Di-D-fructose continues to react and form caramelan‚ caramelen‚ and caramelins‚ which make the sugar

Discussion As expected in the experiment Glucose‚ Fructose‚ and Sucrose were all utilized for fermentation. Based on the rate of evolution of CO2 the yeast was most efficiently able to utilize the substrate Glucose‚ followed by Sucrose and Fructose respectively. Given more time I believe that Sucrose would have surpassed glucose in total rate (ml CO2/hr) as time and energy was taken as the yeasts cells broke Sucrose down into its glucose and Fructose monomers. That being said with all the substrates

Carbohydrates serve as two main objectives in the human body to either help digest foods or to help provide energy. Fiber is a type of carbohydrate is necessary to have a regular digestive system. Majority types of carbohydrates such as sugars and starches can break down glucose to be used as energy. The movie‚ King Corn‚ is about two best friends and an acre of corn in Iowa. A small ear of corn contains 23 grams of carbohydrates. Corn can be transformed and be used in several different ways. In

yeast. The specific variable we tested was the volume of fructose in each vial solution. Hypothesis: The vial with the highest volume of fructose will produce the most carbon dioxide. Null Hypothesis: There will be no difference between the production of carbon dioxide in the different volume vials. Method: While we warmed the 250 ml of water that we eventually put the yeast in‚ we prepared our sugar solutions. Since we used the same sugar (fructose)‚ we used the weight-to-volume ratio to create the sugar
