Q15.94P - Chemistry: Molecular Nature Of Matter And Change

Question

Draw the R group of (a) alanine; (b) histidine; (c) methionine.

Step-by-Step Solution

Answer

1. As a result, alanine's side chain is CH3.    

                                           

      2. As a result, histidine's side chain is,

                                         

       3. As a result, methionine's side chain is,

                                    

                                                 

Step 1:(a) R group of alanine

A carboxylic acid having a protonated amino group on the alpha carbon is known as an amino acid.

An amino acid's general structure is as follows:

                                               

The only difference between amino acids is the substituent linked to the alpha carbon.

Alanine has the following structure: 

                                                       

As a result, alanine's side chain is CH3.

Step2:(b) R group of histidine

Histidine is a very important amino acid. Histidine has the following structure:

                                       

As a result, histidine's side chain is,

                                               

Step3:(c) R group of methionine

An important amino acid is a methionine. Methionine has the following structure: 

                                   

As a result, methionine's side chain is,

                                             

Side chain of methionine
