Dissociation constants of organic

The effect of some organic compounds on the activity of chitinase from Serratia marcescens has been investigated. Among these compounds, 1,10-phenanthroline was found to be an inhibitor and ethanol - an activator of the chitinase activity;
-
’ dipyridyl and Zn2+ do not take any effect on the chitinase activity. In this investigation, the dissociation constant of an chitinase-metalic ion complex (K1) and the inhibition constant (K2) have been estimated with K1 = 0.1 mcM and K2 = 2.667 mM.

Dissociation Constants Of Organic Acids And Bases: This table lists the acid-base dissociation constants of over 600 organic compounds, including many amino acids. All data apply to dilute aqueous solutions and are presented in the form of pKa, which is the negative of the logarithm of the acid dissociation constant Ka.
