General description
7β-hydroxycholesterol (7βOHC) is an oxidized derivative of cholesterol. 7β-hydroxycholesterol-d7 is the deuterated form of 7β-hydroxycholesterol.
Application
7β-hydroxycholesterol-d7 has been used:
- as cholesterol oxidation product for mass spectroscopy analysis
- as an internal standard for spiking white adipose tissue and plasma samples for mass spectroscopy analysis
- as an internal standard working solution in gas chromatography- triple-quadrupole mass spectrometry
- as an isotopically labeled internal standard in tandem mass spectroscopy analysis for plasma sterol quantification
Biochem/physiol Actions
7β-hydroxycholesterol-d7 (7β-OHC) along with 7-ketocholesterol (7-KC) plays a key role in atherogenesis. It is distributed extensively in the arterial compartment of apo- E knockout mice. 7βOHC induces apoptosis via activation of glycogen synthase kinase-3 (GSK3). It also triggers reactive oxygen species (ROS) resulting in mitochondrial dysfunction. 7βOHC favors demyelination and is a potential oxidized oxysterol in X-linked adrenoleukodystrophy (X-ALD) disorder.

Obesity may not be consistently associated with metabolic disorders and mortality later in life, prompting exploration of the challenging concept of healthy obesity. Here, the consumption of a high-fat/high-sucrose (HF/HS) diet produces hyperglycaemia and hypercholesterolaemia, increases oxidative stress, increases endotoxaemia

Background: Oxysterols are bioactive lipids that control cellular cholesterol synthesis, uptake, and exportation besides mediating inflammation and cytotoxicity that modulate the development of atherosclerosis. Aerobic exercise training (AET) prevents and regresses atherosclerosis by the improvement of lipid metabolism, reverse cholesterol

Low-grade inflammation is constitutive of atherosclerosis, and anti-inflammatory therapy inhibiting interleukin-1β (IL-1β) reduces the rate of cardiovascular events. While cholesterol accumulation in atheroma plaque and macrophages is a major driver of the inflammatory process, the role of the LXR cholesterol
