English term or phrase: multiple cytochromes P450
In vitro and in vivo, clopidogrel is metabolized according to two main metabolic pathways: one mediated by esterases and leading to hydrolysis into its inactive carboxylic acid derivative (85% of circulating metabolites), and one mediated by multiple cytochromes P450.

Am o problemă legată de "multiple cytochromes P450"... cum s-ar traduce? Mulţumesc anticipat.

mai multe tipuri/forme de citocrom P450
Explanation:
Caracteristica cea mai importanta a citocromului P450 este reprezentata de marea lui diversitate; membrii acestei "superfamilii" au o larga si sovraponibila specificitate de substrat, precum si capacitatea de a interactiona cu majoritatea structurilor chimice.

Genetic variants of other CYP450 enzymes may also affect the formation of clopidogrel's active metabolite.

Reference: multiple cytochromes P450

Reference information:
Mammals express multiple cytochromes P450 simultaneously in a variety of tissues, including the liver, kidney, lung, adrenal, gonads, brain, and most others. For cytochromes P450 that are expressed in many tissues or cell types, the tissue/cell type-specific expression might be associated with their special physiological roles. Several cytochrome P450 enzymes are found not only in different cell types and tissues, but also in different subcellular compartments. Generally, all mammalian cytochrome P450 enzymes are membrane bound. The two major groups are represented by microsomal cytochromes P450 that reside in the endoplasmic reticulum, and mitochondrial cytochromes P450, that reside in the inner mitochondrial membrane.

Cred că am nevoie de un timp de reflecţie în seara asta :-)
După ce am afişat referinţa şi am recitit fraza ta, am început să am dubii...nu se potriveşte în context.
Sistemul enzimatic citocrom P450 este unul singur (complex, superfamilie, etc.) format din mai multe izoenzime.
Eu aş traduce "mai multe izoenzime ale citocromului P450"...

Între timp, mi-am amintit că izoenzimele respective apar frecvent menţionate ca izoforme...(culmea este că am tradus o mulţime despre izoformele citocromului P450...)

...deci este foarte corect să spui:
numeroase/multiple izoforme are citocromului P450

Iată câteva exemple:
De metabolismul nelfinavirului raspund in vitro multiple izoforme ale citocromului P-450, inclusiv CYP3A.

În organismul uman citocromul P450 există sub diferite izoforme (la momentul actual sunt cunoscute mai mult de 400) codate de o diversitate de gene

Asker: Mulţumesc, Mihaela, deci e OK să spunem tipuri diferite de citocrom?

Asker: Da, probabil că este vorba despre izoenzime. Enzimele sunt mai multe, nu citocromii, înţeleg eu. Gând la gând :)
