8,12-iso-isoprostane F2alpha-VI-d11 (8,12-iso-iPF2alpha-VI-d11) contains 11 deuterium atoms at the 16, 16', 17, 17', 18, 18', 19, 19', 20, 20, and 20 positions. It is intended for use as an internal standard for the quantification of 8,12-iso-iPF2alpha-VI by GC- or LC-mass spectrometry. The relative abundance of...

Diethylstilbestrol (DES) is a synthetic estrogen receptor agonist that was prescribed to pregnant women in the late 1930s. It was banned in 1971 because of possible links to increased risk of breast cancer in mothers along with congenital abnormalities and increased risk of cancer in offspring. DES is structurally...

Mono-unsaturated fatty acids are components of the cellular membranes of autotrophic bacteria. The specific composition and abundance of membrane fatty acids can be used to identify specific genera of bacterial populations in natural environments (e.g., mining lakes, etc.). 7(Z)-Hexadecenoic acid methyl ester is a...

Phosphatidylcholine (PC) species are a common class of phospholipids that comprise the mammalian cell membrane. 1,2-Dioctanoyl PC is a synthetic analog of natural phosphatidylcholine species containing saturated C8:O fatty acids in the sn-1 and sn-2 positions of the glycerol backbone. It exhibits a critical micelle...
