Chapter 2, Problem 36P

Interpretation Introduction

Interpretation:

The difference in the result of re-oxidation of the reduced ribonuclease in the presence and absence of the urea needs to be explained.

Concept introduction:

Amino acids are compounds containing amino as well as acidic group. The general molecular structure of an amino acid is as follows:

${\text{NH}}_{\text{2}}\text{-CHR-COOH}$

Here, R is different group for different amino acids. If there is more than one amino group present in an amino acid, they are considered as basic amino acids and if there is more than one carboxylic group then they are considered as acidic amino acids.

Two or more amino acids combine to form di- or polypeptide chains. Here, peptide bond is the amide bond formed between the two amino acids.
