Carnitine 169-180 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 283-289 31603853-13 2019 Results The ratio of 6-6beta-OHC/cortisol was used as a biomarker to study the taurine and L-carnitine influence on CYP3A4 metabolism of cortisol. Carnitine 91-102 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 116-122
