Sterols of the lobster (Homarus americanus) and the shrimp (Pandalus borealis).

In this study we have analyzed the sterol compositions of two continental shelf species of crustacea, the lobster (Homarus americanus) and the shrimp (Pandalus borealis). Cholesterol was found to be the most abundant sterol in these two species with smaller amounts of desmosterol, 24-methylcholesterol, 24-ethylcholesterol, 24-methylenecholesterol and 22-dehydrocholesterol.
