THE UNSAPONIFIABLE LIPIDS OF BEEF LIVER

Lxxvii. the Unsaponifiable Fraction of Liver

Nonsteroidal components of the unsaponifiable fraction of human liver.

In 1952 Penn (21) described the preparation of an unsaponifiable fraction of liver from cancerbearing patients which gave a serological reaction with sera of cancerous individuals, but usually not with normal serum or serum from persons with noncancerous diseases (12). The difficulty of ob taining sufficient stable test material for extensive cancer screening tests led to the development of a s...

Elution behavior of unsaponifiable lipids with various capillary electrochromatographic stationary phases.

Capillary electrochromatographic (CEC) separations of unsaponifiable lipids, tocopherols (T), tocotrienols (T3), and plant sterols were studied under various conditions. Investigated stationary phases include pentafluorophenylsilica (PFPS), triacontylsilica (TCS), and octadecylsilica (ODS) phases. A baseline separation of four sterols (ergosterol, lanosterol, sitosterol and stigmasterol) on ODS...

Uptake of triacylglycerol-rich lipoproteins of differing triacylglycerol molecular species and unsaponifiable content by liver cells.

The fatty acid composition of dietary oils can modulate the incorporation of triacylglycerol-rich lipoproteins (TRL) into hepatocytes, thus affecting the atherogenicity of these particles. However, nothing is known about the effect of the unsaponifiable fraction of the oils. In the present study, we evaluated the influence of these components on the uptake of TRL by rat primary hepatocytes. TRL...
