Investigations demonstrate fatty acid distribution and phospholipid dynamics in liver subcellular fractions, indicating metabolic variations.

The study aims to investigate the metabolism of sphingomyelin, lecithin, and cephalin in various subcellular fractions of rat liver.
Analyzed fatty acid composition in sphingomyelin from rat liver, focusing on C16:0 and C21 fatty acids.
Measured sphingomyelin percentage in mitochondria, microsomes, and cell sap.
Compared specific activities of sphingomyelin, lecithin, and cephalin at multiple time points after 32Pi injection.
C16:0 and C21 fatty acids were predominant in liver sphingomyelin, with distinct profiles in Sph-F and Sph-S.
Sphingomyelin constituted 0.44% of total phospholipids in mitochondria, while higher percentages were in microsomes and cell sap.
Specific activities of sphingomyelin were lower in mitochondria compared to microsomes, with lecithin and cephalin showing significantly higher activities.

Masako et al. (1969) studied this question.
