Product Overview
Description:
7β-hydroxy Cholesterol-d7 is a stable isotope-labeled internal standard intended for the highly sensitive quantification of 7β-hydroxy cholesterol via GC-MS or LC-MS platforms. The unlabelled analyte is a major cytotoxic oxysterol component found within oxidized low-density lipoproteins that drives concentration-dependent vascular endothelial cell apoptosis and serves as a circulating indicator of coronary disease risk.
Labeling:
Stable isotope-labeled
Synonyms:
(3β,7β)-cholest-5-ene-25,26,26,26,27,27,27-d7-3,7-diol; 349553-97-5; 7beta-hydroxycholesterol-d7; (3S,7R,8S,9S,10R,13R,14S,17R)-10,13-dimethyl-17-[(2R)-6,7,7,7-tetradeuterio-6-(trideuteriomethyl)heptan-2-yl]-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthrene-3,7-diol; 7beta-Hydroxy Cholesterol-d7; Cholest-5-ene-25,26,26,26,27,27,27-d7-3,7-diol, (3ss,7ss)-; (3ss,7ss)-Cholest-5-ene-25,26,26,26,27,27,27-d7-3,7-diol; 7ss-Hydroxycholesterol-25,26,26,26,27,27,27-D7; (3ss,7ss)-Cholest-5-ene-3,7-diol-d7; 7ss-Hydroxycholesterol-d7; 7beta-hydroxy-cholesterol(d7); cholest-5-en-3beta,7beta-diol(d7)
