Summary
Two different isolated skeletal muscles of Japanese quail were
used. The influence of branched chain amino acids on the
fractional rate of protein synthesis (FSR) was evaluated using
14C-tyrosine. The addition of 0.5 mM valine, leucine or
isoleucine to the incubation medium significantly decreased
(P<0.05) the value of FSR in extensor metacarpalis radialis. In
the ambiens muscle only the application of leucine increased the
FSR significantly while valine and isoleucine were without any
effect.
