title: Stereoconfiguration of bisphosphatidic and semilysobisphosphatidic acids from cultured hamster fibroblasts (BHK cells).
abstract: Monolayers of hamster fibroblasts (BHK cells) were incubated in Eagle's minimal essential medium under conditions where an increase in the levels of all cellular bisphosphatidic acids takes place. Bisphosphatidic acid and semilysobisphosphatidic were isolated from these cells and subjected to strong alkaline hydrolysis. Stereochemical analysis of the hydrolysis products revealed that the majority of the molecules of both lipids are derivatives of sn-1-glycerophospho-sn-1'-glycerol, the structure previously found to be the "backbone" of lysobisphosphatidic acid, (bis(monoacylglycerol)phosphate) from BHK cells and other sources. This finding suggests a close metabolic relationship between the three bisphosphatidic acid derivatives of BHK cells.
