Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Number of chiral centers in isoleucine is?
A
1
B
2
C
3
D
4
Explanation: 

Detailed explanation-1: -These two amino acids, isoleucine and threonine, have in common the fact that they have two chiral centers.

Detailed explanation-2: -We can observe that there are a total of two chiral centres in isoleucine at the second and third carbon atoms. Since, there are two chiral centres, we will use our formula to find out the number of optical isomers.

Detailed explanation-3: -Threonine has two chiral centers and therefore four possible stereoisomers.

Detailed explanation-4: -For instance, while some molecules like 2-butanol have one chiral center, defined as a tetrahedral carbon atom with four different substituents attached, several molecules like butane-2, 3-diol have multiple chiral centers.

Detailed explanation-5: -Group I: Nonpolar amino acids Isoleucine is an isomer of leucine, and it contains two chiral carbon atoms.
