15(S)-HETE is unambiguously designated by a shortened version of its IUPAC name viz., 15(S)-hydroxy-5Z,8Z,11Z,13E-eicosatetraenoic acid.In this terminology S refers to the absolute configuration of the chirality of the hydroxy functional group at carbon position 15.
"It's better to err on the side of caution." The one exception to this rule, he said, comes to shelf life and expiration dates. These things, he said, "often measure quality, not safety."
[13] [14] [15] Theoretically there are 211 constitutional isomers and this number rise to 550 isomers if we take the enantiomers into account. [7] To make NPEs, manufacturers treat NP with ethylene oxide under basic conditions. [12]
