formaldehyde molecule
1.Conclusion The effects of Formaldehyde were both a DNA strands breaks and DNA-Protein crosslink, and the latter can work severe genotoxicity on cells, that could be the molecule mechanism of leukemia cause by formaldehyde.
2.At the acid reaction stage the polycondensation reaction was primary and formed the macro-molecule system with the methylene or the ether linkage,and the polymerization formaldehyde decomposed completely,and as the form of methylene glycol participated in condensation reaction.
