Traced studies on metabolism of astaxanthin in Atlantic salmon (salmo salar)
Abstract The present studies were performed to investigate the metabolism of astaxanthin (Ax) in Atlantic salmon, especially in the liver of salmon. The investigations were undertaken in vivo salmon that were fed a diet containing 60 ppm 15, 15′ 14 C‐labelled Ax prior to sacrifice. The samples of bl...
