Differential effects of the chronic and acute zinc exposure on carnitine composition, kinetics of carnitine palmitoyltransferases I (CPT I) and mRNA levels of CPT I isoforms in yellow catfish Pelteobagrus fulvidraco.

Highlights: [•] Waterborne Zn exposure differentially affects carntine composition in fish. [•] Differential effect on CPT I kinetics is found in fish exposed to Zn. [•] Zn differentially affects the mRNA levels of four CPT I isoforms in fish. [•] Zn changes CPT I kinetics via altering its expression and carnitine status. [Copyright &y& Elsevier]
