Elevated production of docosahexaenoic acid in females: potential molecular mechanisms.

abstract：:A method for the simultaneous quantitative analysis of prostaglandin E2 (PGE2) and PGE3 is described. The PG were analyzed by selected ion monitoring as the methyl ester-TMS ether derivatives of PGB2 and PGB3, respectively. The internal standard for the quantification of both species was [3,3,4,4-2H4]PGE2. A linear re...
