Isozyme variations in acetaldehyde dehydrogenase (e.c.1.2.1.3) in human tissues. 1978

S Harada, and D P Agarwal, and H W Goedde

NAD-dependent acetaldehyde dehydrogenase (ALDH) of human tissues was investigated by electrophoresis and enzyme assay. ALDH is located mainly in the liver and kidney. The isozymes consist of at least six different components. Five different phenotypes were found in a total of 68 human liver and kidney specimens. It is likely that three isozyme sets are concerned in determining ALDH types. The distribution of various phenotypes of ALDH isozyme sets is presented.
