Cholesterol and Cholesterol Esters in Mycoplasma

Sterols 1. Cholesterol and Cholesterol Esters

In animal tissues, cholesterol (cholest-5-en-3β-ol) is by far the most abundant member of a family of polycyclic compounds known as sterols (see also our web pages on plant sterols, oxysterols, etc.). It can also be described as a polyisoprenoid or a triterpene because of its biosynthetic origin. It was first recognized as a component of gallstones as long ago as 1770, while the great French li...

I. Cholesterol and Cholesterol Esters in Dog Bile

The colorimetric method for the determination of total cholesterol in dog bile is consistently accurate as checked by the oxidative digitonin method. This method has the further advantages of being simple, rapid and economical. A method for the determination of esterified cholesterol in bile is described and it is shown that there are no esters of cholesterol in normal dog bile.

The interrelationships of serum cholesterol, cholesterol esters and phospholipids in health and in coronary artery disease.

Influence of Cholesterol Esters of Varying Unsaturation

Previous work has shown that cholesterol esters are relatively insoluble (<5 mol%) in bilayer phosphatidylcholine and sphingomyelin systems, but exhibit greater solubility in hexagonal (HII) phase anhydrous phosphatidylcholine systems obtained above 100°C. We examine here the influence of cholesterol esters of varying unsaturation on fully hydrated egg phosphatidylethanolamine systems, which un...
