Abstract

3-Dehydroretinol (vitamin A2) and its long-chain fatty acyl esters have been isolated from hairless mouse liver by high-performance liquid chromatography (HPLC). In adult animals, these compounds amount to 1-2 micrograms/g liver, corresponding to 1-2% of the retinol (vitamin A1) concentration. Studies on the regulation of 3-dehydroretinol levels in liver showed that the age and vitamin A status of the animal affect the levels, but the relative proportions of retinol and 3-dehydroretinol are constant.
