Chapter 21, Problem 27A

Interpretation Introduction

Interpretation:

Glucose and fructose structure needs to be drawn and aldehyde and ketone group needs to be marked.

Concept introduction:

Carbohydrate- Carbohydrates are the naturally occurring organic compound. It consists of carbon, hydrogen, and oxygen. There is the presence of aldehyde, ketone, and polyhydroxy groups.

Glucose and fructose are monosaccharides. The structures are different from the presence of different functional groups.

Answer to Problem 27A

Explanation of Solution

The glucose and fructose are simple carbohydrates. They are classified as monosaccharides contain six-carbon.

The structure of glucose and its aldehyde group is as follows:

The structure of fructose and its ketone group is represented as follows:

Conclusion

The glucose and fructose sugar structure is different due to the presence of aldehyde and ketone group respectively.
