“However, … l-carnitine 1 ) significantly increased beta-oxidation … the oxidation of AA in HPCs and the oxidation of both fatty acids in KCs; 2) decreased the esterification, but did not alter … 3) alleviated the significant competitive inhibition of AA-dependent PGE(2) synthesis and COX-2 expression by EPA.”
“Taken together, the results strongly suggest that l-carnitine affects competition between AA and EPA in PG synthesis in liver cells by enhancing oxidation of EPA in HPCs.”
