Endogenous lipid pool sizes and FA composition

DAG, PC, and TAG amounts present in 13 to 14 mg dry weight developing embryos precultured for 3 d, as measured by ESI-MS/MS. The FA composition is calculated from the molecular species in Figure 1. FA values are represented as mol % among each lipid class.
