Glutathione transferase zeta catalyses the oxygenation of the carcinogen dichloroacetic acid to glyoxylic acid
. Biochem J 331 (pt 2):371-374.
No formic or glyoxylic acid
was detected and the pyruvic:malonic acid molar ratio was <0.05.
Nitrobenzene in the solutions was determined spectrophotometrically (v=38 440 [cm.sup.-1]), while for oxalic acid titration with KMnO4 and for glyoxylic acid
the iodometric method was used.
It consists of a thermal activated hair treatment for curly hair without formaldehyde or glyoxylic acid
, which is said to reduce frizz and curls control.
After removal of the piperidine, 1 mg of the synthesized peptide was carboxymethylated by reaction for 12 h at 0 [degrees]C in dichloromethane containing 0.25 mol/L glyoxylic acid
and 1 mg of sodium cyanoborohydride as described previously (20).
