organic molecules are carbohydrates‚ lipids‚ and proteins. Carbohydrates contain carbon‚ hydrogen and oxygen with a ratio of 1:2:1‚ this means that for every 2 hydrogen atoms there is one carbon atom and one oxygen atom. They are necessary for the body to function properly because they provide the fuel that burns to produce energy. Carbohydrates come in the class of either a monosaccharide‚ disaccharide‚ or polysaccharide. Monosaccharides are the simplest form of a carbohydrate‚ disaccharides are made

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 anaerobic

Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test‚ this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test‚ the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far

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

D_____ J_____ CARBOHYDRATES LAB May 22‚ 2013 Pre-lab Questions 1. The water in test tube No. 1 is a negative control. No reaction is expected to occur because water is not a carbohydrate. Reaction by a negative control is evidence of contamination. 2. The color changes expected for positive test results are Benedict’s test: orange to brick red Tollen’s test: metallic silver Starch iodine test: blue-black 3.

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.

With an improved procedure the question could have been answered with this methodology‚ but the aim was to find out the affect of carbohydrates on blood glucose levels‚ but the methodology provided an answer for the question without going into depth of the biochemistry and carbohydrate structure. This could be solved by amending the aim or by constructing some sort of pre-experiment with the bread that would be used to compare the structure of Danskt Rågbröd

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
