INTERORGAN TRANSPORT AND CATABOLISM OF CARNOSINE AND ANSERINE IN RAINBOW-TROUT

1. After large amounts of carnosine or anserine were injected into rainbow trout white muscle, they were promptly washed out into blood and incorporated mainly into kidney. 2. These dipeptides were transported only a little to the other portions of white muscle but significantly to red muscle. 3. After anserine administration, pi-methyl-L-histidine, a constituent of anserine, increased largely in the kidney, followed by liver and muscles. 4. Histidine, a decomposed product of camosine, increased in muscles after camosine administration prior to the increase in kidney and liver.
