Sucrose

encompasses two experiments involving the effects of secondary metabolites from floral nectar in Bombus impatiens. The first part of the experiment entails infecting the 539 bumblebees with the intestinal parasite Crithidia bombi and feeding them a diet of sucrose and one of eight secondary metabolites. After analyzing cell counts it was found that four of the secondary metabolites, including anabasine, nicotine, catapol and thymol, reduced the levels of infection by 61-81%. The most effective…

Biochemical Unknown I. Introduction Cultural Characteristics or morphology and biochemical tests can be used to identify and classify microorganism. By culturing microorganism in nutrient broth, slants, and on nutrient agar plates, the cultural characteristics or morphology can be determined. In this lab, the test tube 2 was incubated in a nutrient broth. The pigmentation of the tube was yellow. The media for test tube 2 was turbid. There were a few sediment on the bottom of the broth. In…

What does it mean when someone has diabetes? A person with diabetes has a disease in which their blood glucose levels are higher than normal (too high). We intake glucose from the foods that we eat. A hormone called insulin helps glucose get into your cells in order to give them energy. The two forms of diabetes are type 1 and type 2. A person with type one diabetes does not produce insulin for the body. However, for a person with type two diabetes, their body doesn 't make use of insulin well.…

and oxygen. With a structural components such as glucose and sugar. Carbohydrates can be singular molecules such as monosaccharides, or multiple molecules such as disaccharides. Monosaccharides are glucose and fructose, while disaccharides are sucrose and lactose. These function to store energy in the body. Macromolecules…

Types of Macromolecules Lab Report Name: Drasti Patel ID #: 20575017 Partner: Sijia Luo Course: BIOL 130L – 019 Tuesday, 7:30 Room # 151 TA: Ashutosh Patel, Doshina Naila Date of Experiment: September 16, 2014 Date of Submission: September 23, 2014 Introduction: The objective of this lab experiment is to identify different macromolecules by carrying out three different tests such as iodine test, Benedict’s test and the biuret test. These three tests are going to examine…

This experiment determined how solute concentration affected the rate of osmosis in a cell and the outside environment. Three pieces of dialysis tubing were used as three different cells, each filled with different solute concentrations. Each one of the cells was placed in one of three beakers that were filled with tap water. The masses of each of these cells before being placed in the beakers, and afterwards in ten minute intervals for an hour. The percent difference between the initial mass…

enough xylitol to be beneficial. It can be found in some berries, fruit, vegetables, and mushrooms. When regular sugar (sucrose) is consumed it gives the bacteria on your teeth energy to thrive. The bacteria can then multiply and produce acids that will eat away the enamel and produce cavities. Xylitol, a natural sweetener from fibrous parts of plants, does not break down like sucrose. It helps prevent bacteria from sticking to teeth, slowing down tooth decay. The bacteria (Streptococcus mutans)…

entering the small intestines the digestive process continues on the carbohydrates, protein and fat. The turkey cheese lettuce and bread are further broken down by pancreatic amylase digesting the starches breaking them down into disaccharides, lactose, sucrose, and maltose. These are further broken down into monosaccharides, lactose to glucose and galactose. Sucrase to broken down to glucose and fructose. Maltase breaks down to maltose to form 2 molecules of…

The Freezing point of water is 32° fahrenheit, But does anything affect the freezing point of water? The effect of salt and sugar lowering water’s freezing point is called Freezing Point Depression(FPD). When water freezes, its molecules slow down and “stick” together, and eventually slow down so much they stay in place and become a solid. However when salt or sugar is added, it “interferes with the formation of the crystalline bonds between water molecules that give ice its solidity”, Written…

Other groups were assigned with glucose and sucrose. Diluting 1 M of sodium chloride with water made six solutions. The six solutions ranging from 0M to 1M were prepared. These 6 solutions composed of 50 mL of solutions with different concentration of NaCl. The uses of concentrations of NaCl were 0M…
