Phospholipid metabolism in Neisseria gonorrhoeae: phospholipid hydrolysis in nongrowing cells.

abstract：:The seed oil ofEuonymus verrucosus Scop., family Celastraceae, contains more than 90% 1,2-diacyl-3-acetins (monoacetotriglycerides). The constituent triglyceride acids, other than acetic, are the usual long-chain fatty acids.Thin-layer chromatography (TLC), infrared (IR) and hydrolysis with pancreatic lipase indicate ...
