| Biochem/physiol Actions: | 3-Hydroxybutyrate dehydrogenase (3-HBDH), a mitochondrial enzyme, catalyzes the reversible oxidation of 3-hydroxybutyrate (3HB) to acetoacetate, with NAD as coenzyme. In mammals, acetyl-coA is metabolized, in one of two pathways, to produce acetoacetate and D-3-hydroxybutyrate, which along with acetone are known as ketone bodies. 3-HBDH reversibly reduces this free acetoacetate to D-3-hydroxybutyrate. In patients with diabetic ketoacidosis (DKA), the ratio of 3HB and acetoacetate can be as high as 10:1, as compared to the normal ratio of 1:1. 3-HBDH enzyme can be used to detect the quantity of 3HB in urine, serum, and blood samples. |
| General description: | 3-Hydroxybutyrate dehydrogenase (3-HBDH) enzyme, obtained from Rhodobacter sphaeroides, is generally used for the quantification of ketone bodies, such as D-3-hydroxybutyrate and acetoacetate. |
