2-Hydroxybutyric acid
2-Hydroxybutyric acid (α-Hydroxybutyric acid ) is converted from 2-Aminobutyric acid, with 2-oxobutyric acid as an intermediate metabolite. 2-Hydroxybutyric acid is a potential biomarker for type 2 diabetes and preeclampsia[4]. 2-Hydroxybutyric acid prevents the acetaminophen (AP)-induced liver injury[3].
