Significats de sulfate esters en anglès

In contrast, the pregnenolone sulfate ester level was low and did not significantly change among the developmental stages.

These results taken together suggest that the amphibian brain possesses steroidogenic enzyme P450scc and produces pregnenolone and its sulfate ester.

In the present study, seasonal changes in pregnenolone and its sulfate ester were further examined as a possible physiological change using R. nigromaculata.

In humans, dopamine mostly exists in two isomeric forms of sulfate ester conjugates as metabolites; i.e., dopamine-3-O-sulfate and dopamine-4-O-sulfate in the circulation.

Partial structures of anionic components, composed primarily of sulfate esters, were obtained with CID.

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.

Furthermore, several nitroxy-organosulfates originating from monoterpenes were found in the ambient samples.

Conclusions: A more complete structural characterization of polar organosulfates that originate from isoprene secondary organic aerosol was achieved.

These nitroxy-organosulfates were only detected in the nighttime samples, suggesting a role for nighttime chemistry in their formation.

One of the detected organosulfates also occurred in ambient aerosol samples that were collected at a forest site in northeastern Bavaria, Germany.
