α-keto acid

Verified step by step guidance

Identify the structure of glutamine, which is an amino acid with the side chain -CH2-CH2-CONH2.

Understand that transamination involves the transfer of an amino group from an amino acid to a keto acid, resulting in the formation of a new amino acid and a new keto acid.

In the transamination of glutamine, the amino group (NH2) is removed from the alpha carbon (the carbon adjacent to the carboxyl group) and replaced with a keto group (C=O).

The resulting structure after the removal of the amino group from glutamine is an alpha-keto acid. This structure will have a keto group at the alpha position, which is the carbon next to the carboxyl group.

Draw the structure of the alpha-keto acid, ensuring that the alpha carbon now has a keto group (C=O) instead of the amino group (NH2). The rest of the glutamine structure remains unchanged.
