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: -A key feature of amino acids is that the carbon is chiral. When a carbon atom is bound to four unique groups, it creates a chiral center (also known as a stereocenter). Simply put, a chiral molecule is one that cannot be superimposed with its mirror image.
