Would glucose solution produce a positive Benedicts test?
No, Benedicts reagent will show positive results if the carbohydrate is a reducing sugar. You will know if it is positive if the sample will turn from blue to green then to orange when you are cooling the solution, which is the last step when you are performing the benedicts test for carbohydrates.
Why do i have High amylase and low lipase results?
There might be something wrong with your salivary glands.
Why should benzidine reagent be freshly prepared?
Benzidine reagent is used to test blood in urine. It needs to be freshly prepared in order to obtain best results, otherwise, possible contamination may occur.
Why does glycoproteins reacts positively with Molisch reagent?
Glycoproteins give positive results for Molisch's test. This answer is true because Molisch test was a test for sugar.
Is it a valid test if an organism that possesses cytochrome c oxidase and the reagent begins to turn blue at 45 seconds?
No, it is not valid. Results need to be read within 20 seconds because oxygen in the area quickly distorts the results in an experiment of this kind.

Does bromocyclopentane react with magnesium?
Yes, it results in a Grignard reagent.
What are the Benedicts test results for glucose?
the solution will turn a 'brick red' colour if positive but will stay blue if negative.
An unknown sample is tested with both biuret reagent and benedicts reagent both test result in a blue color what has been learned and why are these called negative results?
That the unknown sample is not a monosaccharide and is does not contain peptide bonds (is not a protein). This is because they both produced negative results because Biuret tests positive in solutions that contain peptide bonds and will turn a violet color. Benedict reagent reacts to monosaccharides and will turn green-reddish orange when a monosaccharide is present. Neither of these things happened so the results are negative.

How soon are tzanck preparation results ready?
Results are available the same or following day, often within minutes.
Why you will spray ninhydrin for analysis in chromatography?
Since amino acids are colourless compounds, ninhydrin is used for detecting them. To identify this, after development, the TLC plate is sprayed with ninhydrin reagent and dried in an oven, at 105°C for about 5 minutes. Ninhydrin reacts with α- amino acids that results in purple coloured spots [(due to the formation of the complex - Rheuman's purple).
