Lab BCH2333 Section: 4 (Monday afternoon 1st week) Experiment 1: Carbohydrates Separation Techniques Based on Molecular Size Demonstrator: Date Preformed: January 26th‚ 2015 Date of Submission: February 2nd‚ 2015 Team #: Purpose The purpose of this experiment is essentially two-fold. Two of the four experimental procedures of this laboratory will be used to gain a conceptual and practical understanding of separation techniques used to isolate monomers from their respective polymers. Namely

Through this investigation we found no effect in carbohydrate mouth rinsing on exercise performance. On the contrary to our hypothesis‚ there was no significant difference in distance cycled between those who carbohydrate mouth rinsed and the control (Fig. 1.). In addition‚ we also found that there was no significant difference in HR throughout the entire investigation between treatment groups (Fig. 2.). These exercise performance results is inconsistent with those results obtained by Carter et

Pre-lab 1: Identifying Carbohydrates Abstract The point of this lab is to determine if a substance contains carbohydrates such as a reducing sugar and/or polysaccharides. This will be done by using Benedict’s reagent and Iodine stain tests. Benedict’s reagent will react to reducing substances in the solution by oxidizing it and changing the structure of the reducing sugar to form a colored precipitate. The color of this precipitate can be used to determine the concentration of reducing sugars in

The importance of carbohydrates in living organisms Carbohydrates contain carbon‚ hydrogen and oxygen in the ratio of 1.2.1.. There are many different types of carbohydrate‚ all of which are useful to living organisms. The most important carbohydrate is probable glucose. Glucose is a monosaccharide and is the monomer unit which makes up more complex polysaccharides. Two glucose molecules can be joined in a condensation reaction‚ whereby water is removed‚ for example to produce maltose‚ a disaccharide

Discussion of the Metabolic and Hormonal effects of Very Low Carbohydrate Diets 1.0 Summary Low carbohydrate‚ high protein diets have been raising concerns within medicine for quite some time. There is quite some conflicting evidence regarding the benefits and detrimental effects that these diets may have on metabolic and whole body health. Bone and Calcium loss – Why does a low Carbohydrate diet affect bone? Carbohydrates‚ if highly eliminated from the diet‚ are most frequently replaced with

T2:BIOCHEMISTRY AND ANALYSIS:DETECTION OF FATS‚PROTEINS AND CARBOHYDRATES OBJECTIVE The main purpose of the experiment is to understand some general tests that detect fats‚proteins and carbohydrates in foods. INTRODUCTION Carbohydrates are also known as sacharides. There are 4 main groups of carbohydrates‚which are monosaccharides‚ disaccharides‚ oligosaccharides and polysaccharides. Carbohydrates play an important role in living organism as it is the energy storage‚ and it also plays

The intake of the products high in carbohydrates causes the insulin levels to spike. The high amount of insulin locks the fat which leads to the burning of the glucose instead of the fat. A person loses the most weight during the initial period of the low-carb diets. The reason for this is because the low levels of the insulin in the body causes the kidneys to shed an excessive amount of sodium. Moreover‚ the carbs in the bodies are stored in the form of glycogen. The glycogen binds water molecules
