    Sterol composition and phytosterol utilization and metabolism in the milkweed bug

    Analysis of the sterols of the milkweed bug,Oncopeltus fasciatus (Dallas) and dietary sunflowerseeds revealed that there is little, if any, conversion of dietary C28 or C29 phytosterols to cholesterol in this phy...

    Ecdysone 20-hydroxylase from the midgut of the tobacco hornworm (Manduca sexta L.)

    An ecdysone 20-hydroxylase enzyme system that converts α-ecdysone to 20-hydroxyecdysone was prepared from the midgut of the tobacco hornworm prepupa. This partially purified enzyme is NADPH dependent and is lo...

    Ecdysone metabolism: Ecdysone dehydrogenase-isomerase

    An enzyme system that converts α-ecdysone to its hormonally less active 3α-epimer was detected only in the midgut of the tobacco hornworm,Manduca sexta (L.). This system appears to be specific for the ecdysones a...
