Interpretation Introduction

Interpretation: Each amide group present in oxytocin is to be classified as ${\text{1}}^{\text{o}}$, $2^{\text{o}}$, or $3^{\text{o}}$.

Concept introduction: The amide is identified as primary $\left(1^{°}\right)$, secondary $\left(2^{°}\right)$ and tertiary $\left(3^{°}\right)$. The primary amide is the one in which nitrogen atom is directly attached one carbon atom only. The secondary amide group is the one in which nitrogen atom is directly attached to two carbon atoms. The tertiary amide group is the one in which nitrogen atom is directly is attached to three carbon atoms.
