sentences:  When blood flow to the heart is restricted, the asymmetrical distribution of phosphatidylethanolamine between membrane leaflets is disrupted, and as a result the membrane is disrupted.Additionally, phosphatidylethanolamine plays a role in the secretion of lipoproteins in the liver.This is because vesicles for secretion of very low-density lipoproteins coming off of the Golgi have a significantly higher phosphatidylethanolamine concentration when compared to other vesicles containing very low-density lipoproteins.
