설명

일반 설명

β-Glucuronidase Type H-2 from Helix pomatia is a crude solution of enzymes derived from the Roman snail. Many β-glucuronidases derived from mollusks also contain sulfatase activity.

애플리케이션

β-Glucuronidase from Helix pomatia has been used:

• in the enzymatic treatment of urine samples for liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) analysis
• in the quercetin extraction procedure from pig or rat tissues for high performance liquid chromatography (HPLC) analysis
• in the enzymatic deconjugation step in urine and plasma sample preparation for gas chromatography-mass spectrometry analysis (GC-MS)

β-glucuronidase was used to hydrolyze conjugated glucuronide and sulfate metabolites.

생화학적/생리학적 작용

β-glucuronidase (β-GIc) is an exoglycosidase that catalyzes the breakdown of complex carbohydrates. In humans it converts conjugated bilirubin into the unconjugated form, making bilirubin suitable for reabsorption.

Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis
