columns * Faster‚ Higher‚ Stronger * Fitness and Nutrition News The liver is often overlooked when we consider organs integral to exercise‚ but it is an important reservoir of glycogen‚ the body’s stored form of glucose. All sugars‚ including sucrose‚ or table sugar‚ and high-fructose corn syrup‚ which usually consists of almost equal portions of glucose and fructose‚ are converted into glucose‚ and stored as glycogen‚ in the body. Strenuous exercise diminishes or

Digestive System Hydrolysis of Sucrose After viewing the animation‚ answer these questions: 1. The enzyme sucrase breaks the disaccharide Sucrose into two monosaccharides: Glucose ‚ or sugar‚ and fructose ‚ or fruclose sugar. 2. Where does this reaction occur? This reaction occurs on the surface of the instetina epithelial (mucosal) cell surfaces. 3. For hydrolysis to occur‚ the sucrose must bind to what part of the sucrase enzyme? The sucrose molecule must bind to the active

Yeast and Sugar - The Chemistry must be right Jansen‚ C. Gymnasium Felisenum‚ The Netherlands 14-04-2010 Summary Yeast can metabolize sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. In this experiment yeast ferment sugars anaerobically. When yeast ferments the sugars anaerobically‚ however‚ CO2 production will cause a change in the weight of the sugar/yeast-solution. This raises a further question: What is the effect of different kinds of sugars
Premium Glucose Disaccharide Sugar
Sucrose is a disaccharide formed from D-glucose and D-fructose. The glycosidic linkage is between C1 of glucose and the C2 of fructose. 1H NMR of Sucrose: Mass Spectrum of Sucrose: 13C NMR spectra of sucrose: 3. Why is it difficult to isolate sugars? For simple sugars‚ they are small molecules and they behave similar properties that make them hard to separate. Besides‚ sugars are most electrically neutral. The separation of electrically neutral sugars is a relatively difficult and

are taking up or losing water. Procedure 1. Label six specimen tubes: distilled water‚ 0.1‚ 0.2‚ 0.3‚ 0.4‚ 0.5 mol dm-3. Place approximately one third of a tube of distilled water in the first‚ and an equal volume of each of a series of sucrose solutions of different strengths and (molarities) in the remainder. Each tube should be firmly stoppered. 2. Using a cork borer and a razor blade‚ prepare six solid cylinders of potato. Each cylinder should be approximately 10mm in diameter

per gram (Suzan‚ 620). It is relatively inexpensive to produce‚ so the food industry sees HFCS an easy way to make products less expensive. HFCS is a kind of corn sugar; it is nearly identical to sucrose (table sugar)‚ which is made up of 50 percent glucose and 50 percent fructose (“What”). Sucrose and HFCS contain the same amount of calories and are of equal sweetness. High fructose corn syrup is commonly used in the food supply in the United States and other countries.

graph we can tell how clearly glucose has highest respiration rate of 455 ppm/min. Sucrose is second with 391 ppm/min‚ then fructose with 231 ppm/min and lastly lactose with 92 ppm/min. We can see a clear trend‚ that glucose had the highest rates and that lactose was the lowest‚ so we see a clear downwards sloping trend‚ which was also expected. This suggests that yeast respires best with glucose instead of sucrose fructose or lactose. To explain this process‚ we must first understand how sugar affects
