Answer to Problem 63A
The molecular mass and molecular weight of both glucose and fructose is same.
Fructose contains
Explanation of Solution
Glucose consists of single unit of sugar which can’t be hydrolyzed into simpler molecule. Glucose is obtained by the photosynthesis process and also found in plants.
Fructose consists of single unit of sugar which can’t be hydrolyzed into simpler molecule.
Glucose and fructose are structural isomers of each other implies they have same molecular formula that is
Molecular formula of glucose and fructose =
Molecular weight of glucose and fructose
=
=
Now, the structure of glucose and fructose is:
Glucose
Fructose
Glucose and fructose both have six carbon atoms and five alcohol groups. But, fructose contains ketone (-C=O) functional group whereas glucose contains aldehyde (-CHO) functional group.
