Description générale

2-Aminoisobutyric acid also known as α-aminobutyric acid, is an amino acid used in solution-phase peptide synthesis. It is a desirable building block for peptides because of its strong tendency to cause the peptide to form a helical shape.

Application

2-Aminoisobutyric acid can be used to synthesize self-assembled polypeptide nanoparticles. Incorporation of this compound into the peptide chain can prevent undesired reactions since it is di-α-substituted, and inert to C−H abstraction.
