[Human aldehyde dehydrogenase in a sample of the Costa Rican population]. / Aldehído deshidrogenasa humana en una muestra de la población costarricense.

This is an electrophoretic study of ALDH isozymes in post-mortem tissue extracts. Three different electrophoretic variants of the isozyme ALDH3 were found in the 100 individuals examined. One liver sample showed lack of ALDH1 activity, but it remains unknown whether this is due to genetic mechanisms. The other two isozymes--ALDH2 and ALDH4--did not show any variations.
