Failure of chicken insulin to alter polysaccharide levels of the avian glycogen body

• 1.

  1. In vivo and in vitro studies were carreid out comparing the effects of chicken insulin with those of equal amounts of beef insulin on the glycogen body of the domestic chicken.

• 2.

  2. The glycogen body glycogen moiety was unaltered regardless of experimental design indicating that the constancy of this structure's polysaccharide levels is neither attributable to use of a non-homologous hormone nor to restriction of the hormone by the avian blood-brain barrier.
