- We did an experiment about carbohydrate chemistry and the prof did not elaborate on the details. She just gave the positive result and reagent. I would like to ask the following: Kindly explain the mechanism/principle of the Benedict's test that occurred with the samples (enumerated) Give the chemical equation for each. Glucose Sucrose RiboseHydrolosis of Carbohydrates You can use this as your reference : https://youtu.be/uWIEBKKsaTsA solution was subjected to series of test to identify what carbohydrate/s is/are present. Results were tabulate below. Justify your answer.
- An unknown carbohydrate tested positive for Molisch test and Seliwanoff's test. it tested negative on Barfoed's test and benedict's test. identify the unknown a. Glucose b. sucrose c. Fructose d. LactoseA first year BS Nursing was given an unknown carbohydrate that could be any of the following: Starch, sucrose, arabinose, glucose, or galactose. The results of the analysis were tabulated in the table below. Complete the table by supplying the correct inference. Then identify the composition of the unknown.Based on this video https://www.youtube.com/watch?v=rKng5-ij6kQ Provide a schematic diagram for the Barfoed’s test methodologies in determining the presence of carbohydrates. Also, give the basic principle for the test. (not a graded question, video is very brief)
- What type of carbohydrate is this? Osazone Test Result: Starfish-like structure with distinct bell-shaped features and spikes. Melting point determination resulted in 195 degrees celcius.1. Draw three (3) carbohydrate-containing samples that you can find in your house or community. Identify the specific name of carbohydrate present in each of your example.I. True or False. Write the word “reducing” if the statement is correct,otherwise write “non-reducing”. 1. Mutarotation affects the reducing property ofcarbohydrates.
- A student used 3.9g of liver sample and extracted all the lipids into a total of 1ml of CHCl3. 5 microliters of the total sample was transfered in to a fresh tube and 2ml of ethanol and 2ml of acid-ferric chloride was added. After careful mixing and 30minutes of incubation, absorption of the sample was measured at 550nm. Absorption was 0.55.
