Imino acids are organic compounds that contain a nitrogen atom as part of an amide-like structure. They are structurally similar to amino acids, which contain a carboxyl group and an amino group, but instead of the amino group, imino acids have a structural unit known as an imine or Schiff base, which is a carbon-nitrogen double bond with a hydrogen atom attached to the nitrogen atom.

One example of an imino acid is proline, which is a cyclic imino acid that plays important roles in protein structure and function. Proline is unique among the 20 standard amino acids because its side chain is linked to the nitrogen atom of the backbone, forming a ring-like structure. This structural feature gives proline unique properties, such as restricted rotation around the bond between the nitrogen and alpha carbon atoms, which can affect protein folding and stability.

Other imino acids may be formed through chemical reactions or enzymatic processes, and they can play important roles in various biological pathways, including the biosynthesis of amino acids, nucleotides, and other biomolecules. However, imino acids are not typically considered to be part of the standard set of 20 amino acids that make up proteins.
