Question
Chapter 8, Problem 1E
(a)
Summary Introduction
To determine: The number of stereoisomers possible for a ketopentose.
Concept introduction:
Stereoisomers are the pair of compounds which have the same atom and same chemical formula, but differ in the spatial arrangement of their atoms. One of the pairs of stereoisomers is known as epimer.
(a)
Expert Solution
Answer to Problem 1E
Correct answer: The number of stereoisomers possible for a ketopentose is 4.
Explanation of Solution
Explanation:
The formula to calculate the number of stereoisomers in a given carbohydrate is 2n, where n= number of chiral carbons.
The ketopentose contains two chiral atoms. Therefore, the number of stereoisomers will be 22 = 4.
(b)
Summary Introduction
To determine: The number of stereoisomers possible for a ketohexose.
Concept introduction:
Stereoisomers are the pair of compounds which have the same atom and same chemical formula, but differ in the spatial arrangement of their atoms. One of the pairs of stereoisomers is known as an epimer.
(b)
Expert Solution
Answer to Problem 1E
Correct answer: The number of stereoisomers possible for a ketohexose is 8.
Explanation of Solution
Explanation:
The formula to calculate the number of stereoisomers in a given carbohydrate is 2n, where n= number of chiral carbons.
The ketohexose contains three chiral atoms. Therefore, the number of stereoisomers will be 23 = 8.
(c)
Summary Introduction
To determine: The number of stereoisomers possible for a ketoheptose.
Concept introduction:
Stereoisomers refer to the pair of compounds which have the same atom and same chemical formula, but differ in the spatial arrangement of their atoms. One of the pairs of stereoisomers is known as epimer.
(c)
Expert Solution
Answer to Problem 1E
Correct answer: The number of stereoisomers possible for a ketoheptose is 16.
Explanation of Solution
Explanation:
The formula to calculate the number of stereoisomers in a given carbohydrate is 2n, where, n= number of chiral carbons.
The ketoheptose contains four chiral atoms. Therefore, the number of stereoisomers will be 24 = 16.

Biochemistry Question. Please help. Thank you.
You are studying pyruvate utilization in mammals for ATP production under
aerobic conditions and have synthesized pyruvate with Carbon #1 labelled with radioactive C14.
After only one complete cycle of the TCA cycle, which of the TCA cycle intermediates would be
labeled with C14? Explain your answer.
Interestingly, you find C14 being excreted in the urine. How does it get there?
