Medchemexpress LLC Choline oxidase | 9028-67-5 | 100 U
Choline oxidase (EC 1.1.3.17) is an enzyme that catalyzes the oxidation of choline to glycine betaine via betaine aldehyde in the biosynthesis of glycine betaine. Glycine betaine functions as an osmolyte, and this enzyme shows potential for enzymatic betaine production. The product should be stored under the conditions recommended in the Certificate of Analysis.
- Catalyzes oxidation of choline to glycine betaine
- Involved in glycine betaine biosynthesis
- Potential for enzymatic betaine production
