plastoquinonen.

Brit.

/ˌplastə(ʊ)ˈkwɪnəʊn/, U.S.

/ˌplæstoʊˈkwɪˌnoʊn/,

/ˌplæstoʊˈkwaɪˌnoʊn/

Origin: Formed within English, by compounding. Etymons: chloroplast n., -o- connective, quinone n.

Etymology: < plast- (in chloroplast n.; compare -plast comb. form) + -o- connective + quinone n.

Biochemistry.

Any of a homologous series of compounds which have a quinone nucleus with a terpenoid side chain; spec. one of these occurring in the chloroplasts of plants and involved in electron transfer during photosynthesis.

1958 F. L. Crane in Plant Physiol. 34 547/1 It is proposed that Q₂₅₄ should be called plastoquinone... This name will serve to emphasize the localization in chloroplasts and possibly other plastid structures.

1973 Biochimica et Biophysica Acta 301 36 Several homologues of plastoquinone..have been detected in algae and chloroplasts of higher plants... The detailed chemical structure of plastoquinones B and C is not known yet.

1993 New Scientist 31 July 24/1 (caption) Ubiquinones act as ‘electron shuttles’ in respiration; plastoquinones play a similar role in photosynthesis.
