ME Smith - Biochimica Et Biophysica Acta (BBA)-Lipids and Lipid …, 1968 - Elsevier
The rate of loss of radioactivity of lipids of brain subcellular fractions was followed for 56
days after injection of adult rats with uniformly labeled [14 C] glucose. Myelin did not reach
its maximum specific activity until 5 days after injection, then showed a slow rate of loss of
radioactivity. When the turnover of the lipid components of purified myelin was measured,
inositol phosphatide and lecithin were found to have a more active metabolism than the
other myelin lipids which include serine phosphatide, sphingomyelin, ethanolamine …
