[The enzymatic degradation of DDT. 5. Direct transformation of DDD (dichlorodiphenyldichloroethane) into an aldehyde].

The chemical-preparative preparation of the aldehyde (DDHO) is possible by using of saponification. Its enzymatic formation in the organism of warm-blooded animals has not been described up to now. The identification of the aldehyde after application of DDD to rats was successful, inspite of the inhibition of the HCl-cleaving consecutive reactions, whereby the enzymatic formation of the aldehyde was indicated. A possible reaction mechanism is presented.
