[The metabolism of various acaloric compounds with fatlike properties in rats].

Pseudofats as total substituted long-chain esters and ethers of polyhydroxyl compounds (sucrose, triglycerol, and polyethyleneglycol) are more or less indifferent against gastrointestinal enzymes, but display specific metabolic effects on lipid metabolism especially on cholesterol synthesis in liver, plasma lipid level, and fecal cholesterol excretion. Among the different tested compounds there exist similarities as well as differences, which are to consider as an indication for a specific relationship between structure and effect. These relations are more closely investigated and critically discussed.
