Question

Draw the condensed structural formula for the $\mathrm{\alpha }$-keto acid produced from each of the following in transamination:

a.

b.

Short answer

(a) The condensed formula for the $\mathrm{\alpha }$-keto acid produced is

(b) The condensed formula for the $\mathrm{\alpha }$-keto acid produced is

Step-by-step solution

Part (a) Step 1: Given information

We need to find the condensed formula for the $\mathrm{\alpha }$-keto acid produced from the transamination of given compound i.e.

Part (a) Step 2: Explanation

We know that

When aspartate is transaminated $\mathrm{\alpha }$-keto acid is produced. And a condensed formula is that which represents all the symbols of each element and bonds between them. So, the required $\mathrm{\alpha }$-keto acid is,

Part (b) Step 1: Given information 

We need to find the condensed formula for the $\mathrm{\alpha }$-keto acid produced from the transamination of given compound i.e.

Part (b) Step 2: Explanation 

We know that

When isoleucine is transaminated $\mathrm{\alpha }$-keto acid is produced. And a condensed formula is that which represents all the symbols of each element and bonds between them. So, the required $\mathrm{\alpha }$-keto acid is,
