(1945) The reactions of formaldehyde withamino acids and proteins. Aminoplastics (urea formaldehyde resins and melamine formalde- hyde resins) Reaction of formaldehyde with urea or melamine yields urea formal-dehyde (UF) or melamine formaldehyde (MF) (condensation process).

Research should be directed to the formaldehyde concentrations produc- ing such effects as well as to the skin parameters condition- ing the start of the irritative skin contact reaction.

Since differences in indi-vidual reactions to formaldehyde are large in both the normal popu-lation and in hyperreactive and sensitized persons, it is difficult toestimate a concentration guaranteed not to produce negative reactionsin the general population.

Formaldehyde protects dietary-protein frommicrobial proteolysis in the rumen by reacting with free amino groupsin the protein, forming inter- and intramolecular methylene bridges(Siddons et al., 1982).

8.7.1 Reactions with macromolecules Formaldehyde reacts readily with a variety of cellular nucleo-philes, including glutathione, forming adducts of varying stability(Feldman, 1973; Uotila & Koivusalo, 1974; McGhee & von Hippel, 1975).

Formaldehyde also reacts with proteins (French & Edsall, 1945) andnucleic acids (Haselkorn & Doty, 1961; Lewin, 1966; Collins & Guild,1968; Feldman, 1973; Chaw et al., 1980); it reacts with single-strandDNA, but not with double-stranded DNA.

4.2.1 Special products of degradation under specific conditions Highly carcinogenic bis(chloromethyl)ether can be produced by acondensation reaction between formaldehyde and hydrogen chloride(Thiess et al., 1973; Nelson, 1977; Albert et al., 1982; Sellakumar etal., 1985).
