[36] Hydrolysis of the sulfuric acid esters of steroid compounds

1969
Publisher Summary This chapter describes two methods (methods A and B) for the hydrolysis of the sulfuric acid esters of steroid compounds. Method A is an assay method employing radioactive substrate that is based on the hydrolysis of 3H- or 14C-labeled steroid sulfate substrate of known specific activity followed by selective recovery of the product

[Mechanisms of anticoagulant effect of chitosan sulfuric acid ester].

Voprosy meditsinskoi khimii, 1993
Anticoagulation effect of chitosan sulfate ester and some mechanisms of its influence on hemostasis were studied in vitro. The chitosan sulfate ester catalyzed more effectively inactivation of the enzymes involved in the inner pathway of blood coagulation affecting only slightly the activity of outer pathway factors.
