What are some of the limitation of the Benedict's test on sugars?
The limitations are it doesn't react with all small sugars. The test does not allow for you to determine which sample sugar is present. The test is qualitative which allow you to only detect the presence of a certain molecule.
Why Rothera's test not used to detect beta hydroxy butryic acid?
rothera's test is positive only for ketone bodies, having a keto group, that is, c=o group. beta hydroxy butyrate has its c=o group reduced to c-oh. hence, the test becomes negative.
Why dont polysaccharides give a positive test with Fehling's solution?
Fehling test is only suitable for reducing sugars, that means, monosaccharides in its open form with an aldehyd available. Polysacchardes have the aldehydes in a acetal form and they can not react
What makes up table sugar?
Carbon, hydrogen and oxygen are the only elements that make up sugars.
Can metals have positive and negative oxidation numbers?
No, they can't only have positive oxidation numbers in compounds.
Do sugars have nitrogen?
No. Sugars are composed of carbon, hydrogen, and oxygen, but not nitrogen.
Why use only D sugars are biologically important?
. whyOnly D sugars are biologically important?
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.
Are amino acids the building block of sugar?
A better comparison would be that amino acids make up protein similarly to the way that sugar makes up starch. Fat is not composed only of sugars.

Do enzymes break down into simple sugars?
No, protein is broken down into amino acids. Simple sugars are only formed when carbohydrates are digested.
Are proteins bonded together resulting in simple sugars?
No. Sugars are carbohydrates.
Are natural sugars harmful sugars?
Generally Not. Only sugar naturally in fruits should be eaten. Overconsumption of sugar can cause many diseases. Further it is empty calories. Meaning that when you eat foods sweetened with extra sugar like candy, you are consuming calories with little if any nutritional value. Also sugar is bad for your teeth.
Is a negative plus a positive a positive?
If, and only if the positive value is > the negative value.
Can the absolute value be positive or negative?
Only positive.
What are the building blocks of simple sugars?
Simple sugars are themselves building blocks of either complex sugars or carbohydrates. Glycol aldehyde is an example of a pre biotic simple sugar.
