Occurrence of dolichol in human tissues

The concentration of dolichol has been determined in various human tissues obtained at autopsy. The highest levels ( 3000 microgram/g wet weight) were found in testes. Liver and several other endocrine tissues contained about 1000 microgram/g. Lower levels were present in other tissues examines. Only a small proportion of the total dolichol in human tissues was esterified to fatty acids.
