In contrast, the pregnenolone sulfateester level was low and did not significantly change among the developmental stages.
2
These results taken together suggest that the amphibian brain possesses steroidogenic enzyme P450scc and produces pregnenolone and its sulfateester.
3
In the present study, seasonal changes in pregnenolone and its sulfateester were further examined as a possible physiological change using R. nigromaculata.
4
In humans, dopamine mostly exists in two isomeric forms of sulfateester conjugates as metabolites; i.e., dopamine-3-O-sulfate and dopamine-4-O-sulfate in the circulation.

1
An important atmospheric finding is the presence of an organosulfate that is related to methyl vinyl ketone, a major gas-phase oxidation product of isoprene.
2
Furthermore, several nitroxy-organosulfates originating from monoterpenes were found in the ambient samples.
3
Conclusions: A more complete structural characterization of polar organosulfates that originate from isoprene secondary organic aerosol was achieved.
4
These nitroxy-organosulfates were only detected in the nighttime samples, suggesting a role for nighttime chemistry in their formation.
5
One of the detected organosulfates also occurred in ambient aerosol samples that were collected at a forest site in northeastern Bavaria, Germany.
