Metabolism of Cholesta-4,7-dien-3-one and Cholesta-4,6-dien-3-one by Mouse Liver Microsomes.

The administration to rats of cholesta-3:5-dien-7-one.

The fact that cholesta-3:5-dien-7-one occurs in arteriosclerotic aorta and some other tissues, in small amounts (Hardegger, Ruzicka & Tagmann, 1943; Prelog, Ruzicka & Stein, 1943), and that it is not necessarily an artifact (Kantiengar & Morton, 1955a) makes it desirable to study the effect of administering it to animals.

Stability of Cholesterol; Cholesterol-5β,6β-Epoxide; Cholesta-3,5-Dien-7-One, and 5α-Cholestane in Solution During Short-Term Storage

Because cholesterol and its oxide products (COPs) are used as standards during analysis, their stability and autoxidation were assessed under typical storage conditions. Individual toluene solutions of cholesterol; cholesterol5β, 6β-epoxide; cholesta-3,5-dien-7-one; and 5α-cholestane were prepared and aliquots were stored at 23 ± 2°C, 4°C, and -20°C for 7 days. Samples were removed from storage...
