Abstract
The lipid that accumulated in the adrenal cortex of a patient who had been treated with aminoglutethimide has been compared with the lipid in normal human adrenal cortex and identified as esters of cholesterol with fatty acids. While the concentration of free cholesterol was normal, that of esterified cholesterol was three times greater than that in normal controls. Sterols were analyzed by gas chromatography and found to consist almost wholly of cholesterol. The fatty acid composition of the cholesterol esters in adrenal cortex from patients with abnormal steroid secretion rates was determined. An increased proportion of cholesteryl arachidonate (cholesteryl-3β-[allcis]-eicosa-5,8,11,14-tetraenoate) was found in adrenal cortex from patients with decreased steroid secretion rates and a decreased proportion in adrenal cortex from patients with steroid secretion rates raised sufficiently to cause Cushing's Syndrome.
