During sleep there is a two- to threefold increase in the incorporation of inorganic orthophosphate-(32)P into a chemical fraction of the brain of the 20-day-old rat. This increase is not in the lipids or nucleic acids, but is associated with an acid-labile phosphate entity of the tissue residue after extraction of these fractions and phosphorus-containing substances of low molecular weight.
在睡眠期间，20日龄大鼠大脑中无机正磷酸 -（32）P掺入某一化学组分的量增加了两到三倍。这种增加并非发生在脂质或核酸中，而是与在提取这些组分及低分子量含磷物质后组织残渣中一种酸不稳定的磷酸实体有关。
