title: 1-Docosanol and other long chain primary alcohols in developing rat brain.
abstract: Long chain alcohols were detected in developing rat brain at ages ranging from 5 to 40 days. They were at their highest level of 0.0109% of the total lipids at the age of 10 days and decreased to 0.0036% at the age of 40 days. They consited mainly of hexadecanol, octadecanol, octadecenol, eicosanol, docosanol, and tetracosanol. The fact that substantial amounts of fatty alcohols having more than 20 carbon atoms were present in myelinating rat brain indicated a chain length specificity in their utilization for 0'alkyl and 0'alk-1-enyl glycerolipid biosynthesis.
