Summary

The rate of turnover of individual P-compounds, related to the metabolic cycle of some phosphatides, was followedin vivo in the brain of rats a few days old after32P administration. The phosphorylcholine is the precursor of the cytidinediphosphatecholine; this in turn may be the precursor of lecithin. Thel-α-glyceryl-phosphorylcholine represents the degredation product of lecithin. The specific activity curves of the phosphorylethanolamine and phosphorylse rine are similar to that of the phosphorylcholine; likewise thel-α-glycerylphos-phorylethanolamine is similar to the activity curve of thel-α-glycerylphosphorylcholine.
