title: Effect of supplemental glucose or sucrose on liver and carcass glycogen metabolism of young chicks.
abstract: An experiment was conducted with Leghorn chicks to evaluate the effect of glucose or sucrose on liver and carcass glycogen. Phosphorylase a and synthase a were assayed to learn if glycogen cycle enzymes could be influenced by the early plane of nutrition. Both glucose and sucrose in drinking water increased liver and carcass glycogen in 3-day-old chicks. Groups given sucrose had more liver glycogen than groups given glucose after 5 days. Supplementary glucose given to fed chicks resulted in an increase in glycogen synthase a and a decrease in glycogen phosphorylase a at 4 days of age. By 6 days of age, differences in synthase activity between groups given sucrose or glucose were small. However, glucose solutions decreased phosphorylase a activity. The relationship between synthase a and phosphorylase a also partially regulates glycogen metabolism.
