Chapter 21, Problem 63A

Interpretation Introduction

Interpretation:

Six-carbon ketone sugars needs to be identified.

Concept introduction:

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

Sugar contains different number of carbon chain, for example glucose contains six-carbon, sucrose contains twelve-carbons, etc.

Answer to Problem 63A

Ketohexoses term is used for the six-carbon ketone sugar.

Explanation of Solution

Ketohexoses sugar contains six-carbon and ketone as a functional group. In the carbohydrate the carbonyl group is present in aldehyde, ketone, and alcohol group present as a polyhydroxy group.

Conclusion

In the carbohydrate sugar form is present with the carbonyl group as aldehyde or ketone, and termed as ketohexoses or aldohexoses sugar.
