Chemical. CAS 4249-19-8. Formula C4H9NO2. MW 103.12. Synthetic Beta-Aminoisobutyric acid is a non-protein amino acid originating from the catabolism of thymine and valine. beta-Aminoisobutyric acid occurs in two isomeric forms and both enantiomers of beta-Aminoisobutyric acid can be detected in human urine and plasma. In plasma, the S-enantiomer is the predominant type due to active renal reabsorption. In contrast, urine almost exclusively contains the R-enantiomer of beta-Aminoisobutyric acid, which is eliminated both by filtration and tubular secretion. The S-enantiomer of beta-Aminoisobutyric acid is predominantly derived from the catabolism of valine, the R-enantiomer is the product of the catabolism of the pyrimidine bases uracil and thymine by the enzyme dihydropyrimidine dehydrogenase DPD, in what constitutes the first step of the pyrimidine degradation pathway.
