Cholesteryl Fatty Acid Esters and Free Cholesterol in Food of Animal Origin

European Journal of Lipid Science and Technology, Volume 128, Issue 1, January 2026.
Cholesterol occurs in free (bioavailable) and esterified (transport/storage) forms. Here, we present a method that allows both forms to be determined independently. Finally, the quantities of free and esterified cholesterol were determined in several meat, animal fat, and cheese samples.

Deposition of Cholesterol and Cholestanol in Experimental Rabbit Atherosclerosis.

Experimental Biology and Medicine, 1961
SummaryContrary to the original findings it is established that cholesterol-C14 and cholesterol-H3 are deposited in tissues of rabbits in exactly the same way. The reason for the discrepancy in deposition of the two substances in earlier experiments was found in the presence of chemically negligible traces of cholestanol-H3 which had then not been ...

Arabidopsis root lipid droplets are hubs for membrane homeostasis under heat stress, and triterpenoid synthesis and storage

New Phytologist, Volume 249, Issue 2, Page 892-916, January 2026.
Summary Plant lipid droplets (LDs) and their associated proteins have numerous subcellular and physiological functions. While considerable progress has been made for LDs in many tissues, the function and composition of LDs in roots remain largely unexplored.

Separation of cholesterol from its companions, cholestanol and Δ7-choleatenol, by thin-layer chromatography

Journal of Lipid Research, 1965
A two-step thin-layer chromatographic procedure is described for separation of cholesterol from its naturally occurring companions. Impregnation of Silica Gel G with silver nitrate retards cholesterol relative to cholestan-3Β-ol and Δ7-cholestenol, which

The intracellular distribution of sterols in Eurycotis floridana and its possible relation to subcellular membrane structures

Journal of Lipid Research, 1966
The roach Eurycotis floridana was reared on a semisynthetic diet containing minimal cholesterol-4-14C (0.005%) supplemented with cholestanol-7α-3H (0.1%), and various tissues of the insect were separated into ``nuclear,'' ``mitochondrial,'' and ...

Increased plasma cholestanol and 5 alpha-saturated plant sterol derivatives in subjects with sitosterolemia and xanthomatosis.

Journal of Lipid Research, 1985
We have measured plasma sterol composition in 14 subjects with sitosterolemia and xanthomatosis. In addition to elevated plasma phytosterol (campesterol 16 +/- 7 mg/dl and sitosterol 35 +/- 16 mg/dl) and normal to moderately high cholesterol levels (258 +

Comparison of the metabolism of cholesterol, cholestanol, and β-sitosterol in L-cell mouse fibroblasts

Journal of Lipid Research, 1971
The following data have been obtained from comparative studies on the metabolism of cholesterol, cholestanol, and β-sitosterol by L-cell mouse fibroblasts.

Increased plasma plant sterol levels in heterozygotes with sitosterolemia and xanthomatosis.

Journal of Lipid Research, 1990
Plasma sterol levels in a family of sitosterolemia and xanthomatosis were determined by a high performance liquid chromatography. Three affected siblings manifested marked xanthomatosis including subcutaneous soft tissues and generalized atherosclerosis.

Lethal atherosclerosis associated with abnormal plasma and tissue sterol composition in sitosterolemia with xanthomatosis.

Journal of Lipid Research, 1985
Tissue sterol composition was determined in an 18-year-old male with sitosterolemia with xanthomatosis who died suddenly and whose coronary and aortic vessels showed extensive atherosclerosis and, for comparison, in an 18-year-old male with minimal ...

Experimental cholelithiasis in the rabbit induced by cholestanol feeding: effect of neomycin treatment on bile composition and gallstone formation

Journal of Lipid Research, 1968
Fed cholestanol is converted by the rabbit to 5α-bile acids which coprecipitate with the normally occurring 5β-bile acids to form gallstones composed of calcium and sodium glycoallodeoxycholate and glycodeoxycholate.
