General description

7α-hydroxycholesterol is an oxysterol synthesized by the oxidation of the side chain of cholesterol. It is the precursor of bile acid.

Application

7α-hydroxycholesterol (D7) may be used:
  • as a deuterated sterol standard for the extraction of lipids from cultured cells
  • in liquid chromatography-high-resolution mass spectrometry method (LC-MS/HR-MS) for the quantification
  • to synthesize d4-7 -hydroxy-3-oxo-4-cholestenoic acid (d4-7-HOCA)

Packaging

2 mL Amber Glass Sealed Ampule (LM4103-1EA)

Oxysterols are important intermediates in numerous metabolic and catabolic pathways and their biological significance is also proven. The present paper describes a reliable and short liquid chromatography-high-resolution mass spectrometry method (LC-MS/HR-MS) for the quantification of 8 different oxysterols (24(S)-hydroxycholesterol, 25-hydroxycholesterol
