In the first part of the lab, 5 solutions were tested for the Benedict’s test along with Iodine test, what was observed was the reaction rate vs. enzyme concentration. As shown on the plot #1 graph, the concentration of the salivary amylase increases, the faster it turned into light brown, meaning the faster it broke down into glucose subunits. Specifically, in test tube 11, it contained 2ml of 10% salivary amylase and 2ml of the buffer, this solution turned into a light brown in 25 seconds. This
monosaccharides. They may also contain either a ketone or aldehyde functional group (King, 2014). Some examples of monosaccharide include- glucose, galactose and fructose. Disaccharides are part of oligosaccharides-they contain 2 monomer units - maltose is made of 2 glucose molecules, lactose made of a galactose and glucose molecule and sucrose which consists of a glucose and fructose molecule serve as some examples. They are bound together by 1, 4 glycosidic bonds. Cellulose, starch and glycogen are examples
bodies by breaking it down, and making glucose. Glucose is a sugar that our body uses to give us energy. Carbohydrates generally provide us with fiber, vitamins and minerals. There are two kinds of carbohydrates: simple and complex. We get our simple carbohydrates from foods such as milk, lactose products, fruit, and sugar. Complex carbohydrates, on the other hand, come from starches like cereal, bread, beans, potatoes, and starchy vegetables. The benedict test is used to indicate the reducing property
iLab #2 Carbohydrate Tests INTRODUCTION - For this experiment we will be testing four different bacteria with four different tests, using glucose, lactose, and sucrose. Hopefully we will use the information from those test to be able to identify the organisms in each of the samples from the case studies. We will use the results from the four different tests along with the information of how different bacteria react to match up to the case
chemicals. To carry out the lab, three different tests were performed: The Iodine test, Benedict’s test and Biuret test. The twelve chemicals that were being tested on throughout the experiment included: 1% glucose solution, 0.3% glucose-1-phosphate, 1% maltose sugar, honey solution, 1% sucrose solution, 1% lactose solution, 1% glycogen solution, 1% starch solution, protein, beer, distilled water and an unknown substance “unknown 193”. The Benedict’s test was intended to check if the twelve chemicals
unknown microorganism through several differential media tests. Over the course of a couple weeks, ten tests were performed. First, a gram stain was performed, indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next, a negative result in the methyl red test indicated that no mixed acid fermentation occurred. The DNase test was performed and yielded a positive result. The SIM test provided two outcomes, that the bacterium did not reduce
The purpose of this laboratory exercise was to perform tests necessary to be able to distinguish one microorganism from 10 others. Using a series of biochemical tests and characteristics, unknown #22 was concluded to be Pseudomonas aeruginosa. A dichotomous key was mapped out and used during this process. Using this provided guidance as well as organization as to what the result may be. Upon obtaining the unknown organism, it was important to make a streak plate of the bacteria on TSA. The purpose
Observed reactions and recorded in the table below. Cleaned out the 5 test tubes. Data: Iodine Test Results Discussion: The iodine test was successful. Potato juice and starch were the only two substances containing starch. Again, glucose and onion juice contains glucose, while water doesn't contain starch or glucose and was just tested to make sure the test was done properly. SUDAN III TEST Introduction: Sudan III test detects the hydrocarbon groups that are remaining in the molecule. Due
Present 1. What specific part of the kidney does the dialysis tubing represent? What is the function of this part? It represents the part of the kidney that acts like a semipermeable membrane, the nephrons. The nephrons are made of membranous tubules that act analogously to the semipermeable dialysis bag. When blood passes through the tubules, particles in the blood leave the tubule by the process of diffusion. 2. What does the yellow food color represent at the end of the experiment? What does the
gestational diabetes in previous pregnancies. Pregnant women don’t need to have had diabetes before in order to develop gestational diabetes. They can just have high blood glucose levels during pregnancy to get gestational diabetes. There is a process in which the baby has to go through inside their mother’s womb. The placenta is what supports the baby as it grows. Hormones from the placenta help the baby develop. But these hormones also block the action of the mother 's insulin in her body. This problem
