Web14 apr. 2024 · Similarly, hepatic PLIN5 retains the dietary excess of FAs in LDs and blocks lipolysis, which protect hepatic from IR damage induced by HFD feeding . Likewise, it was proposed that hepatocytes possess segregated mitochondria, which would be dedicated to sustaining dietary FA esterification into TGs but also to producing new FAs and … WebPartially purified preparations of rat liver lipoxygenase, free of hemoglobin, exhibited a dioxygenase activity of 223.1 +/- 65.9 nmoles/min/mg protein and co-oxidase activity of 6.1 +/- 0.5 nmoles/min/mg protein toward benzidine. These results suggest that hepatic lipoxygenase may play an important role in the metabolism of this hepatocarcinogen.
