Erucin and SFN are interconverted
by human metabolism and show comparable bioactivity in vivo.
The new work suggests an alternative possibility: that cancer cells are not fixed at all, but that, at any given point in time, they exist in one of several phenotypic "states" and those states can interconvert
cholerae O1 strains as have been demonstrated to interconvert
and to undergo serotype switching between Ogawa and Inaba.
A reference which suggests that each enantiomer is equally responsible for the side effects or which indicates that the enantiomers are likely to interconvert
vitiates any motive to separate the enantiomers.
Arsenite and arsenate generally interconvert
in urine depending on handling and storage conditions, and the sum of the two is generally used to measure inorganic arsenic in urine.
Thalidomide is a racemic glutamic acid analogue composed of two enantiomers R- and S-thalidomide (stereoisomers that are mirror images of one another) which interconvert
under physiological conditions.
Animals are unable to synthesize n-6 or n-3 fatty acids de novo or to interconvert
one series of fatty acids to another.
To verify that folates do not interconvert
during WB hemolysis, we added 1 folate form at a time to a series of WB hemolysates generated from 1 donor sample at pH 4.0 or pH 4.7: 10 t~,g/L 5CH3THF, 2.5 t~,g/L 5CHOTHF, 5 t~,g/L THF, and 2.5 t~,g/L 5,10CH=THF.
If development of an equivalent square dimension is successful, it could be applied to interconvert
kiln-drying as well as air-drying times between logs and square timbers.
Because all three measures were not consistently taken, we developed the following regressions to interconvert
These data suggest that CCA-adding and poly(A) polymerase activities were able to interconvert
early in evolution, with the CCA-adding enzyme degenerating into a simple poly(A) polymerase, or poly(A) polymerase acquiring the additional specificity required to synthesize a defined sequence of defined length.
Carnot was the first to consider carefully the way in which heat and work interconvert
. For that reason he is considered the founder of the science of thermodynamics (from Greek words meaning "the flow of heat").
