Template:infobox gene cytochrome p450 3a5 is a protein that in humans is encoded by the cyp3a5 gene cyp3a5 encodes a member of the cytochrome p450 superfamily of enzymes like most of the cytochrome p450, the cyp3a5 is expressed in the prostate and the liver.
Cyp2d6, a member of the cytochrome p450 mixed-function oxidase system, is one of considerable variation exists in the efficiency and amount of cyp2d6 enzyme produced between individuals. P450 enzyme cyp2d6 is of importance in medicinal chemistry, pharmacology and medicine to name one such reason, the individual variation of cyp2d6 expression among the human population. Each cytochrome p450 gene is named with cyp, indicating that it is part of the cytochrome p450 gene family the gene is also given a number associated with a specific group within the gene family, a letter representing the gene's subfamily, and a number assigned to the specific gene within the subfamily. Background the impact of polymorphic cytochrome p450 cyp2d6 enzyme on oxycodone's metabolism and clinical efficacy is currently being discussed however, there are only spare data from. Method: the main polymorphisms on the cytochrome p450 (cyp) genes, cyp2a6, cyp2b6, cyp2c19, cyp2d6, cyp3a4 and cyp3a5, and the multi-drug resistance 1 gene (mdr1.
Cyp2d6 metabolizes more than 25% of all drugs, including tamoxifen, many antidepressants, antipsychotics, beta-blockers, and opioids detecting variants of the cyp2d6 gene that cause altered. Цитохром p450 3a4 (скратено cyp3a4) (ec 1141397), е важен ензим во организмот, кој воглавно е присутен во црниот дроб и во цревата врши оксидација на малите страни молекули (ксенобиотици), како што се токсините или лековите, со цел да бидат исфрлени од организмот. Cyp3a4 klinik kullanımda bulunan birçok ilacın metabolize edilmesinde etkilidir ayrıca, cyp2d6 ile metabolize edilen bir ilacın konsantrasyonu arttığında metabolizması yüksek kapasiteli.
