Unit Definition

1 U corresponds to the amount of enzyme which hydrolyzes 1 μmol acetic acid per minute at pH 7.4 and 40 °C (triacetin, Cat. No. 90240 as substrate) 50 U as described above are equivalent to ~1 U using triolein, Cat. No. 62314 as substrate, at pH 8.0 and 40 °C

Other Notes

Selective acylation and deacylation of furanose and pyranose derivatives; Enantioselective hydrolysis of 2-methyl 3-acetoxy esters; Resolution of the diols of bicycloheptane and bicyclooctane by enzymic hydrolysis; Glyceride synthesis
