Sterol Composition in Larvae of the Silkworm, Bombyx mori

Sterols in silkworm larvae were analyzed. Cholesterol was predominantly detected in all tissues examined. Dietary phytosterols and desmosterol, a putative biosynthetic intermediate from phytosterols to cholesterol, were also detected, indicating that imperfect intestinal conversion from phytosterols to cholesterol influences the sterol composition in larval tissues.
