Sucrose

beverages. HFCS, otherwise known as High Fructose Corn Syrup, and sucrose, otherwise known as raw sugar or table sugar, are what has scientists and dieticians worried about the increase of childhood obesity rates in the U.S,. These sugars come from near the equator, and also all over the tropical world. Both HFCS and sucrose are made of glucose and fructose molecules, which they both have in roughly equal amounts. HFCS and sucrose are virtually chemically equivalent. Dr. Robert Lustig, well…

In this lab report a number of tests and results will be discussed. Unknown labs are performed for many reasons ranging from figuring out the causative agent in a diseased patient, to knowing the correct microorganism to use when making certain foods and antibiotics. Unknown labs are a key to testing the knowledge a student has gained throughout the course. Materials: Microscope Bunsen Burner Beaker Test Tube Holder Test Tube Clothes pin Striker Loops and Needles Distilled Water Crystal…

first weighed the sugar (sucrose) to .75g and added it to the beaker. Then we added 37.5 mL of water. Next we added 200μL of sodium phosphate (NaPO3-) and 37.5mL of 10% weight by volume liquid baking soda. We measured the pH. Then we added .25g of dry yeast. Next we placed a CO2 probe in the beaker and measured the CO2 output over a period of 30 minutes. We are measuring the CO2 output as a factor of the growth rate. For the water (neutral) trial, we weighed out .75g of sucrose and put in the…

diseases. In lecture, we discussed and observed pictures of fructose, being a hexose monosaccharide. On the other hand, refined sugars are normally processed food products such as sugar cane (Cancercenter). It is typically found as the disaccharide sucrose, which is a combination of glucose and fructose. These extracted sugars are added to foods such as cookies, cake and soda. Cookies, cake and soda are examples of foods that contain extra sugar that eventually ends up being stored as fat. In…

pressure while painting the surface of the medium to ensure correct results. Also incubate the agar slant at 37˚C for about 48 hours. The third test that was performed was a fermentation test for sucrose. Using the inoculating loop, transfer an inoculum of the suspected microbe into a phenol red sucrose broth. Mix the inoculum and the broth then incubate it within 48 hours at 37˚C. Urease test was the last biochemical test that was performed this day. A urea tablet was added using the tweezers…

themselves in an orderly and repetitive pattern. But the molecules are too small for us to see moving around and arranging themselves. And the dissolving process involves two steps first the water molecules have to bind to the sucrose molecules and second the water molecules pull the sucrose molecules away from the crystals and into the solution. In general there should only be a certain amount of…

explain the accuracy of your prediction. The classification for sugar is polar covalent. Sucrose is a polar covalent solid. Sucrose had a relatively low melting point but was soluble in water. The low boiling point and the hydrocarbon structure meant that it was a covalent and the ability for it to have dissolved in water meant that the molecule must have been polar, making it polar covalent. In a sucrose molecule the two simple sugar molecules bond in such a way that allows freedom of…

prepare a glucose-testing strip. The glucose strip has an aqua color to begin with. If there is glucose present in the solution, the color can range from brown to green instead of aqua. When the six minutes are up, dip the testing strip into the sucrose solution enough that it immerses the tip, then immediately remove. Wait one minute to match the color of the tip to the coloration key on the glucose testing strip bottle and record the amount of glucose present according to the…

LB (mineral oil), MD (aluminum), WC (oak), and PA (corn starch); the Russian people shall receive LC ( isopropyl alcohol), MC (brass), WA (poplar), and PC (salt); the people of the U.S. will receive LE (corn syrup), MF (lead), WB (balsa), and PF (sucrose); the Australian…

In her article “Is Sugar Really THAT Bad For Us?” Jordanna Levin addresses the negative effects of fructose, including weight gain, a risk of type 2 diabetes, and sugar addiction. The article took a negative stance on sugar as in “Sugar is poison” and “Sugar is killing us” (Levin, 2017). Published on a website called “I Quit Sugar”, the article aims to persuade people to completely eliminate sugar from their diet with the help of their “I Quit Sugar 8-Weeks Program”. However, the article is…
