Product Overview
Description:
EOS-d9 (d18:1-d9/32:0/18:2) is a highly specialized, deuterated stable isotope internal standard designed for the precise mass spectrometric quantification of native EOS ceramides. The corresponding unlabeled molecule is a crucial ultra-long-chain esterified ceramide within the mammalian stratum corneum that undergoes sequential, highly specific lipoxygenase-mediated oxygenation and hydrolysis to covalently bind the corneocyte protein envelope, sealing the epidermal barrier against water loss.
Labeling:
Stable isotope-labeled
Synonyms:
(9Z,12Z)-9,12-octadecadienoic acid, 32-[[(1S,2R,3E)-2-hydroxy-1-(hydroxymethyl)-3-heptadecen-1-yl-14,14,15,15,16,16,17,17,17-d9]amino]-32-oxodotriacontyl ester; N-(32-linoleoyloxy-dotriacontanoyl)-Sphingosine-d9; 2692624-26-1
