Abstract
Summary
1. The effect of a single dose of choline on total lipid phosphorus, lecithin P, and cephalin P of mitochondria, nuclei and homogenates of the liver was studied in choline deficient rats. 2. Administration of single dose of choline 40, 75 and 150 mg significantly increased in 6 hours the total lipid P. and lecithin P concentration of liver mitochondira. 3. A statistically significant increase in total lipid P and lecithin P of liver mitochondria and homogenates occurred in 3, 6, 10 and 18 hours following administration of a single dose of choline. 4. Diets low in protein reduce the level of total lipid P, lecithin P and cephalin P in liver mitochondria.
