Answer to Problem 29.1P
The other three structures of l-isoleucine is,
The
Explanation of Solution
The structure of l-isoleucine is,
Figure 1
L-leucine has two stereogenic centers.
Maximum number of stereoisomers possible is calculated by the formula,
Where,
• n is the number of stereogenic center.
Substitute the value of stereogenic centres in the above equation.
The
The structures of other stereoisomers are,
