Abstract

The content and intensity of metabolism of phosphate groups of various phospholipids (phosphatidylcholines, monophophoinositides, aminophospholipids) were studied in homogenate, microsomes, and cytosol of the rat brain under normal conditions and in hypoxic hypoxia (240 mm Hg). The concentration of phospholipids per milligram protein was found to be highest in the microsomes and lowest in the cytosol, but the total phospholipids of the cytosol had the highest metabolic rate of their free phosphate groups. Hypoxia, while not affecting the phospholipid concentration, depressed the intensity of their metabolism; this depression of metabolism, moreover, was about equal in all the tissue preparations studied.
