Table 2.

Individual fatty acyl groups of the major molecular species of PC, PE and PI of soybean seeds. Data were obtained by ESI-MS/MS in negative product ion scanning mode. Each PL species was determined to be a combination of two 18:n fatty acyl chains. PL species levels are indicated as mean mole % of that diacyl combination ± SD (n = 5) and differentiated at p < 0.05 among fresh wild type seed, aged wild type seed, fresh PLD-KD, and aged PLD-KD seed.
