Impact of Cholesterol on Voids in Phospholipid Membranes [PDF]
, 2004 Free volume pockets or voids are important to many biological processes in cell membranes. Free volume fluctuations are a prerequisite for diffusion of lipids and other macromolecules in lipid bilayers. Permeation of small solutes across a membrane, as well as diffusion of solutes in the membrane interior are further examples of phenomena where voids ...

Cholesterol oxides inhibit cholesterol esterification by lecithin: cholesterol acyl transferase [PDF]
Brazilian Journal of Pharmaceutical Sciences, 2009 Cholesterol oxides are atherogenic and can affect the activity of diverse important enzymes for the lipidic metabolism. The effect of 7β-hydroxycholesterol, 7-ketocholesterol, 25-hydroxycholesterol, cholestan-3β,5α,6β-triol,5,6β ...

Tracking cell cholesterol with cholesterol oxidase.
Journal of Lipid Research, 1992 Sterols are ubiquitous and essential constituents of all eukaryotic cells, found either esterified and stored in droplet form (l), or unesterified and integrated into bilayers (2) . Sterols not only play a major structural role in membranes, but serve as precursors for steroid hormones and bile acids (3). The distribution of cholesterol within the cell

Cholesterol and Cholesterol Esters in Mycoplasma [PDF]
Journal of General Microbiology, 1965 Free and esterified cholesterol were determined in the lipid extract of nine parasitic and saprophytic Mycoplasma strains. The saprophytic strains were usally free from esterified cholesterol. Esterified cholesterol was found in the parasitic strains at a ratio of 1:8 to 1:3 to free cholesterol; in the growth medium the ratio was about 4:1 [4-14C ...

Breaking the Cycle, Cholesterol Cycling, and Synapse Damage in Response to Amyloid-ß [PDF]
, 2017 Soluble amyloid-β (Aβ) oligomers, a key driver of pathogenesis in Alzheimer disease, bind to cellular prion proteins (PrPC) expressed on synaptosomes resulting in increased cholesterol concentrations, movement of cytoplasmic phospholipase A2 (cPLA2) to ...

Inhibition of pancreatic cholesterol esterase reduces cholesterol absorption in the hamster [PDF]
, 2004 BACKGROUND: Pancreatic cholesterol esterase has three proposed functions in the intestine: 1) to control the bioavailability of cholesterol from dietary cholesterol esters; 2) to contribute to incorporation of cholesterol into mixed micelles; and 3) to ...
