to further characterize the apparent relationship between squalene epoxidase activity and membrane fatty acid composition , a variety of unsaturated fatty acids differing in their chain lengths and in the positions and orientation ( cis or trans ) of their double bonds were tested for their ability to promote turnover of endogenous squalene in cells previously deprived of olefinic supplements .
