Research investigates sphingomyelin composition in erythrocytes and plasma, highlighting fatty acid differences.

The aim is to separate and analyze different types of sphingomyelins in human erythrocytes and plasma.
Separated lipids using silica gel G TLC technique.
Conducted IR analysis and paper chromatography for structural comparison.
Performed GLC analysis to determine fatty acid composition.
Utilized acid hydrolysis and performic acid-HIO4 cleavage for further investigations.
Identified two types of sphingomyelins with different fatty acid compositions.
Fast moving sphingomyelins predominantly contained fatty acids higher than C20.
Slow moving sphingomyelins were enriched in palmitic and stearic acids.
Phosphorus ratios of fast to slow moving sphingomyelin were 2.6 in plasma and 3.2 in erythrocytes.

Osamu et al. (1967) studied this question.
