TL;DR: Zonal centrifugation has been used to isolate a fraction from bovine liver which appears to be derived from the Golgi apparatus, and which has very high levels of galactosyl transferase.

TL;DR: It is suggested that mitochondria from different sources contain characteristic lipids, mainly phospholipids, of which cardiolipin is particularly diagnostic of the source of the mitochondria.

TL;DR: Golgi apparatus isolated from both rat liver and rat kidney have been characterized with respect to their neutral and phospholipid content and their phosphopipid composition and compared with mitochondria, rough endoplasmic reticulum and plasma membranes.

TL;DR: The Golgi complex of rat liver was shown to contain both phospholipase A1 and A2 activities acting on exogenous phosphatidylethanolamine, the activity of the former being somewhat larger.

TL;DR: The endoplasmic reticulum appears to be the principal site in the cell for the synthesis of sphingomyelin, CDPdiglycerides, phosphatidylinositol, phosph atidylserine and the formation of lecithin, and Interestingly, the biosynthesis of phosphatidsserine appears toBe four times more active in rough than in smooth microsomes, which might suggest a ribosomal localization of this process.
