Would raffinose react with benedicts reagent?
Benedicts reagent tests for reducing sugars, so the question is, is raffinose a reducing sugar. Raffinose is a trisaccharide made up of glucose, fructose and galactose. It is not a reducing sugar because all of its anomeric carbons are bonded, so it will not react with benedicts reagent.
What indicators are used for each molecule simple sugars starches lipids proteins?
Simple sugars: Benedict's solution test for reducing sugars. Starches: Iodine test, which turns blue-black in the presence of starch. Lipids: Sudan IV test, where lipids turn a red color. Proteins: Biuret test, leading to a color change from blue to purple in the presence of proteins.
Is blood qualitative or quantitative variation?
Blood can show both qualitative and quantitative variations. Qualitative variations refer to differences in the composition of blood components, such as the presence of abnormal cells or proteins. Quantitative variations refer to differences in the numerical levels of blood components, like white blood cell count or hemoglobin levels.
How does Benedicts test indicate hydrolysis of sucrose and starch?
Benedict 's solution contains Copper , which can accept electrons from reducing sugars and consequently change color. A positive Benedict's sugar test will produce an orange to brick-red color. Reducing sugars have either a free aldehyde functional group or a free ketone functional group as part of their molecular structure; starches and other polysaccharides lack these functional groups . If Benedict's test changes color ( pos. reaction ) polysaccharides must be hydrolyzed.
What is difference between Qualitative PCR and Quatitative PCR?
In qualitative PCR specific DNA fragment is detected while in quantitative PCR our target DNA sequence not only is detected but its amount is determined (after reaction we can calculate the amount of DNA we had in our sample)

Is a flame test a qualitative or quantitative test?
The flame test in analytical chemistry is only qualitative.
Why Benedict's qualitative test is called semi quantitative?
The Benedict's qualitative test is called semi-qualitative since it is not totally conclusive.
Which is more sensitive test fehlings test or Benedicts test?
Benedict's test is more sensitive than Fehling's test for detecting reducing sugars in a sample. Benedict's reagent has a lower detection threshold and is known to give more accurate results compared to Fehling's reagent.
What is the test for a disaccharide?
It's the qualitative test.
Difference between quantitative and qualitative test?
Qualitative test represents the substance and a quantitative test shows the amount.First Deals with descriptions, second one with numbers
Why should you add 8 drops of urine in the Benedict test?
why should you add 8 drops of urine in the Benedicts test
What are the disadvantages of qualitative testing?
It takes too long for a doctor to perform during a patients consultation. Also the results could be inaccurate if there were any substances left in the test tubes.
Is the flame test a qualitative or quantitative test for the identity of an unknown?
just looking at the color of the flame --- qualitative
Why is the MPN test qualitative?
The test is considered qualitative because you are looking for a negative or a positive test . A example is looking for change of colour in the brilliant green bile broth tubes.
Is pre test and post test qualitative data collection?
yes
