...We have been working with the various enzymes involved in the biosynthesis and breakdown of methylglyoxal (Ray and Ray, 1981, 1982a, 1983, 1984a, 1987)....

...The enzymes responsible for the formation of methylglyoxal have been purified from several sources (Hopper and Cooper, 1972; Ray and Ray, 1981, 1983, 1987; Murata et al., 1985)....

...The Ki’s for D- and L-lactaldehydes were calculated to be 0·46 mM and 1·67 mM, respectively (figure not presented)....

...Because L-lactaldehyde is formed from methylglyoxal in goat liver by the highly active methylglyoxal reductase (Ray and Ray, 1984a), the inhibition of glyoxalase I by L-lactaldehyde, although weak compared to that by the D-isomer, may have some physiological role to play in the regulation of…...

...Inhibition of yeast and goat liver glyoxalase I by D- and L-lactaldehydes It has been reported that lactaldehyde is a strong inhibitor of glyoxalase I (Ting et al., 1965)....

...When 1 mM methylglyoxal was used as substrate the goat liver enzyme was inhibited by 50% by 1 mM L-lactaldehyde, whereas the same degree of inhibition was obtained with only 0·02 mM D-lactaldehyde for the same concentration of methylglyoxal....

...Methylglyoxal was measured either by the 2,4-dinitrophenylhydrazine alkali colour reaction or by using the enzyme glyoxalase I and monitoring the formation of S-D-lactoylglutathione at 240 nm (Cooper, 1975)....

...In some cases the enzyme activity was measured by following the utilization of the substrate methylglyoxal; after the desired period of incubation the remaining methylglyoxal was estimated colorimetrically by the 2,4-dinitrophenylhydrazine alkali reaction (Cooper, 1975)....
