Question

Quizplus · Accepted Answer

The dipeptides Ala-Gly and Gly-Ala are constitutional isomers because they have the same chemical formula (C5H10N2O3) but different arrangements of their constituent atoms. Specifically, in Ala-Gly, alanine (Ala) is bonded to glycine (Gly) through its amino group, while in Gly-Ala, glycine is bonded to alanine through its carboxyl group.
