4. Liver alcohol dehydrogenase (LADH) catalyzes a reversible, pH-dependent oxidation of an alcohol
to an aldehyde according to the following reaction:
LADH
RCH2OH
+
NAD*
RCHO
+
NADH
+
H*
where NAD* and NADH are, respectively, the oxidized and reduced forms of the cofactor nicotin-amide
adenine dinucleotide. While the reaction is actually a two-substrate reaction, it proceeds like a one-
substrate reaction through a so-called compulsory-ordered ternary complex mechanism. It has been
shown through kinetic studies that, in the case of primary alcohols, the enzyme binds first the cofactor
forming a binary enzyme-NAD* complex that then binds the second substrate, the alcohol, to form a
ternary enzyme-NAD*-substrate complex in which the oxidation of the alcohol proceeds with reduction
of the cofactor.
While the enzyme catalyzes oxidation of various steroids as well as ingested ethanol, it also catalyzes
the oxidation of methanol CH3OH, forming the extremely toxic product formaldehyde HCHO.…
