Descrição geral

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.

Aplicação

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.

A procedure is described for the determination of alpha-methyldopa (MD) [L-3-(3,4-dihydroxyphenyl)-2-methylalanine], its metabolite and catecholamines in the urine and plasma of patients undergoing MD therapy, by high-performance liquid chromatography with dual working electrode coulometric detection. An efficient sample preparation procedure

Amine-containing mixed-matrix membranes incorporated with amino-functionalized multi-walled carbon nanotubes (AF-MWNTs) were synthesized for CO2/H2 separation based on the facilitated transport mechanism. AF-MWNTs were chosen primarily as the mechanical reinforcing filler to enhance the membrane stability. At 107 °C and 0.2-MPa

Four oligopeptides consisting of a sequence of alpha-aminoisobutyric acid (Aib) residues, thiolated at either the N- or C-terminus by means of a -(CH(2))(2)-SH anchor, were self-assembled on mercury, which is a substrate known to impart a high fluidity to self-assembled

Short peptides are important as lead compounds and molecular probes in drug discovery and chemical biology, but their well-known drawbacks, such as high conformational flexibility, protease lability, poor bioavailability and short half-lives in vivo, have prevented their potential from being

We use mixed classical/quantum simulations to study the time dependence of an excitation of a C=O vibration on a 3-10 helix of α-aminoisobutyric acid, a system which represents a test case for the formation of self-trapped vibrational excitation states on
