The composition of CNS myelin was investigated in rats adrenalectomized at day 14 and killed 7 days later, previously shown to result in a 25% reduction in the amount of bulk-isolated myelin and a 40% decrease in brain glycerol 3-phosphate dehydrogenase activity. The proportions of the major myelin proteins, as well as the specific activity of 2',3'-cyclic nucleotide 3'-phosphohydrolase, were the same in the myelin from both adrenalectomized and control animals. The amount of total phospholipid and the proportions of individual phospholipids were also normal in myelin from the adrenalectomized animals. The amount of nonmyelin phospholipid in whole brain was unchanged by adrenalectomy. Labeling studies carried out 4 days after adrenalectomy of 14-day-old animals showed no change in the synthesis rates of the major myelin phospholipids as compared with the synthesis rate of nonmyelin phospholipids. Furthermore, incorporation of [1,(3)-14C]glycerol into the glycerol moiety of ethanolamine plasmalogen, which requires glycerol 3-phosphate dehydrogenase, was also normal, showing that the reduced oligodendroglial glycerol 3-phosphate dehydrogenase activity following adrenalectomy was not rate-limiting for myelin phospholipid synthesis.
