Effect of supplemental glucose or sucrose on liver and carcass glycogen metabolism of young chicks.
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.
