Descrizione

Descrizione generale

Echinenone is a carotenoid with a conjugated carbonyl group.[1] Echinenone (4-keto-β-carotene) is a monoketo compound, is an intermediate between β-carotene and canthaxanthin in animals.[2] It is one of the major carotenoids of Anabaena sp.,[3] and also present in Micrococcus roseus.[2] It is located in the thylakoid membrane of Anabaena. The conversion of β-carotene to echinenone is catalysed by CrtO, a β-carotene ketolase.[3]

Applicazioni

Echinenone may be used as an external standard for the extraction of carotenoid from plasma samples.[4] It may also been used as an internal standard, added to samples for extraction and quantification.[5][6]

Azioni biochim/fisiol

Echinenone binds to glocobacter rhodopsin and functions as a light harvesting antenna in Gloeobacter violaceous.[7]
