Fatty acid composition of phospholipids from mitochondria isolated from ygr110wΔ mutant and wild-type cells

Phospholipids were extracted, and fatty acid methyl esters were isolated and quantified as described under “Experimental Procedures.” Results represent the means ± S.D. of at least three analyzes performed with two separate mitochondrial preparations. PC, phosphatidylcholine; PE, phosphatidylethanolamine; PI, phosphatidylinositol; PS, phosphatidylserine.
