Similarly, in yeast, PI has a ... percentage of saturated fatty acid(52–53%) [10] (see also below) and, as observed in other higher eukaryotes, unsaturated acyl chains are mainlylinked to the sn-2 position and saturated fatty acidgroups ... observed and, in contrast, it appearedthat the phospholipid distribution (and particularly the abundance of PI) was similar in wild-type and mutantcells (Table 1). Therefore, it appears that, whatever...
