| Biochem/physiol Actions: | Formaldehyde is the simplest aldehyde that denatures the bihelical regions of RNA and converts the polynucleotides into random coils. It is a genotoxic substance that significantly induces DNA-protein crosslinks (DPC), sister-chromatid exchanges, micronuclei formation and leads to cytotoxicity. It also induces tumors in the nasal epithelium of rats and supposed to be a human carcinogen. |
