Likewise, an increase in ethanolamine (data not shown) and its phosphate was also observed, possibly due to degradation of phosphatidyl ethanolamine
, another component of the plasma membrane.
Literature indicates that sphingomyelin (SM), phosphatidylcholine (PC), and phosphatidylserine (PS) increase while phosphatidyl ethanolamine
(PE) decrease occurred among different stage patients with hypertension; those phospholipids in plasma are mainly derived from blood platelets and erythrocyte membrane phospholipids.
Some lipids are produced as a compensatory mechanism and they fulfill a protective role, such as c16-ceramide, PS, sphingomyelin (SM), phosphatidyl ethanolamine
(PE), and phosphatidylethanol.
Commercial lecithin is a mixture of several natural phospholipids (phosphatidyl choline, phosphatidyl inositol, phosphatidyl ethanolamine
, and phosphatidic acid) in oil.
Lecithin consists of phosphatidyl choline, phosphatidyl ethanolamine
, phosphatidyl serine, and phosphatidyl inositol and some other substances such as triglycerides and fatty acids .
