Q15.95 P - Chemistry: Molecular Nature Of Matter And Change

Question

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

Step-by-Step Solution

Answer

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

        c. Tyrosine's side chain is,

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:

General Amino Acid Structure

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

Glycine has the following structure:

Glycine

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

Step 2: (b) R group of isoleucine

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

Isoleucine

As a result, the isoleucine side chain is,

Step 3: (c) R group of tyrosine

Alkyl group in Tyrosine

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

Tyrosine in phenolic nature

As a result, tyrosine's side chain is,

Tyrosine side chain
