Question

Draw the R group of (a) glycine; (b) isoleucine; (c) tyrosine.

Short answer

1. Glycine's side chain is H.
2. The isoleucine side chain is,

3. Tyrosine's side chain is,

Step-by-step solution

Step 1:(a) R group of glycine

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

Glycine has the following structure:

As a result, glycine's side chain is H.

Step2:(b) R group of isoleucine

The amino acid isoleucine, which is required for life. Isoleucine has the following structure:

As a result, the isoleucine side chain is,

Step3:(c) R group of tyrosine

Tyrosine is phenolic in nature. Tyrosine has the following structure:

As a result, tyrosine's side chain is,
