Sucrose is used to sweeten foods, and provide short term energy. In sodas such as the orange soda and clear soda used during this lab, the sugar is used to sweeten the drink. Density can be used in order to find the sugar concentration in a particular solution. Density is known as the amount of mass that will fit into a certain volume. For this lab, the density of water will be 1 gram/cubic centimeter.
This allows your body to pass starch through without turning it into glucose. Without starch, fat cannot be stored in the form of carbohydrates and less weight will be gained. This may sound too good to be true. Though carb-cutter does actually block amylase, there are many other factors that go into the breakdown of the carbohydrates. Students at the University of Georgia have taken it upon them to test this rumor and see if carb-cutter really stops the breakdown of starch to helps weight loss.
Review the effect of pH on enzyme function. Students should understand that enzymes function best at specific pH levels (which vary depending on the enzyme). Non-optimal pH levels can affect the shape of the enzyme, thereby decreasing its effectiveness as a catalyst. Extreme pH levels can permanently denature the enzyme protein, whereas less extreme pH conditions may only temporarily alter . Lactase is effective at pH 2 – 7 (including dH2O) and therefore breaks down the lactose sugar in milk into glucose and galactose.
The synthesis of NaCl further identified the ionic compound by reacting sodium hydroxide and hydrochloric acid and obtaining solid sodium chloride. The synthesized compound formed was used to perform another flame test and the chloride anion test, which further solidified the identification of NaCl as the ionic compound. Introduction The purpose of the experiment was to identify unknown ionic compound
The starch is used to replicate the starch intake from the plants the caterpillar ingests. Since sugars are insoluble, plants convert them to starches to store them. In the first setup, where no amylase is present, there is no passage of starch from the inside of the tubing to the beaker, however, the Lugols is demonstrated to be a small enough molecule to travel across the membrane, demonstrated by the color change of the inside of the tubing from a cloudy white to a dark blue, a sign of reaction between the Lugol and starch. Once the caterpillar eats the starches, the digestive enzyme amylase breaks down the starch into the original, insoluble sugar. The sugar molecule is now small enough to travel across the membrane to the less concentrated area.
We recorded the observations of color changes that occurred when mixing the solutions into a data table. The next thing we did in our experiment was to blend a McDonald’s happy meal and add an unmeasured amount of water to the so called “McMush”. We conducted the experiment, with the goal of determining if the solutions contained starch, chloride, protein, or glucose and recorded our results in a data table. After analyzing the data concluded from the experiment we concluded that the McMush solution did not contain protein, glucose, or chloride because there were no color changes that matched the conclusions of our previously results. We also concluded that the McMush did have starch because when it was mixed with the solutions, it turned completely black which matched the data from our previously data table.
Chelsea Ferrer TA: Durning Concentrations of Starch in Protein Solutions Many health supplement companies promote a “pure protein” supplement, with only small amounts of starches used as a homogenization agent and as a method to improve taste. How much is a “small amount” though? Investigating exactly how much of a supplement is starches can give the consumer a better idea at what kind of product they are buying – one higher in protein, or one higher in not so healthy taste. To discover the concentration of starch, absorbance values for each unknown protein solution were compared to a standard curve of a 0.1 g/L stock solution of starch. The (C1)(V1)=(C2)(V2) formula was used to determine how much to dilute the 0.1 g/L stock starch solution.
Nutrition and Supplements These nutritional tips may help reduce symptoms: * Eliminate all suspected food allergens, including dairy, wheat (gluten), soy, chocolate, corn, preservatives, and food additives. Your health care provider may want to test you for food allergies. * Eat more antioxidant rich foods (such as green, leafy vegetables and peppers) and fruits (such as blueberries, tomatoes, and cherries). * Avoid refined foods, such as white breads, pastas, and sugar. * Eat fewer red meats and more lean meats, cold water fish, tofu (soy, if no allergy) or beans for protein.
Nutrition Label Assignment NTR 100 Due: September 10th This assignment will help in the understanding of the information on the nutritional label of foods and beverages. Select a food or beverage. You may not select a "nutritional supplement type food or beverage (example a Power Bar or Monster Drink). You may not select a simplified item like sugar, bottled water, a can of soda or cooking oil. Your food must contain at least two macronutrients.
