(r)3hydroxyisobutyric acid

(R)-3-Hydroxyisobutyric acid is a chiral organic compound and a metabolite derived from the amino acid L-valine and thymine catabolism. (R)-3-Hydroxyisobutyric acid is classified as a beta hydroxy acid and functions as a key intermediate in metabolic pathways involving L-valine and thymine. Elevated levels of (R)-3-Hydroxyisobutyric acid, also known as 3-HIBA, may serve as a diagnostic biomarker for severe inherited metabolic disorders, including 3-hydroxyisobutyric aciduria.

3-Hydroxyisobutyric acid is an intermediate metabolite in the pathways of L-valine and thymine metabolism and can be detected in urine. 3-Hydroxyisobutyric acid functions as a secreted mediator of endothelial cell fatty acid transport and insulin resistance. 3-Hydroxyisobutyric acid additionally inhibits key enzymes involved in energy metabolism within the cerebral cortex of young rats. The levels of 3-Hydroxyisobutyric acid are closely associated with multiple pathological conditions, including 3-hydroxyisobutyric aciduria, diabetes, and ketoacidosis. 3-Hydroxyisobutyric acid is therefore valuable for metabolic disease, endocrinology, and mitochondrial energy metabolism investigations.

(R)-3-Hydroxyisobutyric acid sodium is a biochemical marker of the metabolic disorder, 3-hydroxyisobutyric aciduria, characterized by increased concentrations in urine.
