Input (English): Heptamegaly usually results from Cori's disease and Andersen's disease, both of which occur due to dysfunctional enzymes involved in the synthesis of this compound. One enzyme involved with the breakdown of this compound uses pyridoxal phosphate at catalytic sites and only acts on the alpha 1-4 bonds; a branching enzyme is required to eliminate alpha (*) 1-6 linkages and create a linear polymer. During its synthesis, the action of uridyl transferase forms a pyrophosphate intermediate in addition to UDP-glucose. In hepatocytes, a high level of insulin prevents the breakdown of this compound, a degradation promoted by glucagon. For 10 points, name this animal analogue of starch.
Output (English): Science
