General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in starch hydrolysis research. For more information see the article in biofiles.

Unit Definition

1 U corresponds to the amount of enzyme which liberates 1 μmol maltose per minute at pH 6.0 and 25 °C (starch acc. to Zulkowsky, Cat. No. 85642, as substrate).

Other Notes

Molecular weight; Product distribution in the hydrolysis of amylose; Application in (selective) hydrolysis/condensation of glycosidic bonds; Suitable for use in thiamine determination.
