Test: Biomolecules Level - 4 - Question 1

Which of the following compounds will form an osazone derivative?

Detailed Solution for Test: Biomolecules Level - 4 - Question 1

When sugars are reacted with excess of phenylhydrazine osazone formation takes place.

Osazone will form in that sugar only where keto hydroxy group is present.

Thus CH3​CH2​COCH2​OH will form an osazone derivative; as it has keto hydroxy group.

*Multiple options can be correct
Test: Biomolecules Level - 4 - Question 2

Which of the following pairs give the same osazone?

*Multiple options can be correct
Test: Biomolecules Level - 4 - Question 3

 on epimerization with base gives 

Test: Biomolecules Level - 4 - Question 4

D-glucose and D-galactose are:

Detailed Solution for Test: Biomolecules Level - 4 - Question 4

Epimers are carbohydrates which vary in one position for the placement of the -OH group. The best examples are for D-glucose and D-galactose. Both monosaccharides are D-sugars, meaning that the -OH group on carbon-5 of these hexoses is located on the right in Fischer Projection.

 

*Multiple options can be correct
Test: Biomolecules Level - 4 - Question 5

Which of the following pairs form the same osazone?

Detailed Solution for Test: Biomolecules Level - 4 - Question 5

When sugars react with an excess of phenylhydrazine, a class of compounds known as osazone is formed. 

 

Glucose and fructose differ in the arrangement of atoms around the C−1 and C−2 carbon. When both of them react with three molecules of phenylhydrazine, the formation of osazone crystals makes the difference between the carbon atoms in their chain and hence they form the same osazone.

Test: Biomolecules Level - 4 - Question 28

How many of the following are reducing sugar:

Sucrose, Lactose, Maltose, Glucose, Galactose, Fructose, Glycogen, Ribose.


Detailed Solution for Test: Biomolecules Level - 4 - Question 28

The aldehyde group of aldoses is very susceptible to oxidation, whereas ketoses are less so, but can easily be oxidized if, like fructose, they contain an α-hydroxyl and can tautomerize to an aldose. Most monosaccharides are reducing sugars. This includes all of the common ones galactose, glucose, fructose, ribose, xylose, and mannose. Some disaccharides, such as lactose and maltose are reducing sugars since they have at least one anomeric carbon free, allowing that part of the sugar to linearize and yield an aldose.
