일반 설명

Echinenone is a carotenoid with a conjugated carbonyl group. Echinenone (4-keto-β-carotene) is a monoketo compound, is an intermediate between β-carotene and canthaxanthin in animals. It is one of the major carotenoids of Anabaena sp., and also present in Micrococcus roseus. It is located in the thylakoid membrane of Anabaena. The conversion of β-carotene to echinenone is catalysed by CrtO, a β-carotene ketolase.

애플리케이션

Echinenone may be used as an external standard for the extraction of carotenoid from plasma samples. It may also been used as an internal standard, added to samples for extraction and quantification.

생화학적/생리학적 작용

Echinenone binds to glocobacter rhodopsin and functions as a light harvesting antenna in Gloeobacter violaceous.

The mechanisms of main tomato carotenes (phytoene, phytofluene, lycopene and β-carotene) intestinal absorption are still only partly understood. We thus compared carotene bioavailability in mice after gavage with carotene-rich oil-in-water emulsions. We also determined each carotene absorption profile along the
