However, much remains to be investigated, especially with respect to its isomeric
bioaccumulation patterns and its possible toxicological effects on non-target organisms in the environment.
Sensitive and qualitative analysis of isomeric
and isobaric plant metabolites was achieved by developing a MRM and MRM-dependent product ion scan (PIS) method.

and odd-numbered forms in plasma and tissues," Journal ofLipid Research, vol.
[gamma]-halo-[delta]-lactones 3,5,7, the typical principal products of the reaction, were not divided chromatographically into enantiomers, even at retention times of more than 60 minutes.
Combination of pulmonary and systemic venous anomalies in heterotaxic or isomeric
patient is not an uncommon feature but presence of full blown pulmonary and systemic venous anomalies in a single patient is extremely rare.

The miotic activity of urethanes derived from the isomeric
(i.e., redividerdromic) pair of verbal
tol, on the other hand, had isomeric
growth, with an R2 of over 0.95 (Table V)
Although it has been postulated that CLA can modulate the expression of TNFa through the transcription factor NF-b, but it is possible that CLA may act through different mechanisms/regulatory pathways that are further dependent on the isomeric
form of CLA.
