Input (English): Resistance to this chemical is highly correlated with polycystic ovary syndrome. A modification of this compound that has undergone a glycine-asparagine substitution and had two arganines added to its B chain is commercially important because it readily hexamerizes and this chemical is stored as an inactive hexamer. This signal molecule is activated by removal of its (*) C peptide component to promote the dephosphorylation of acetyl-CoA carboxylase. When this enzyme binds to its tyrosine kinase receptor, GLUT's are activated to facilitate trans-membrane import of a substance whose export is facilitated by this hormone's agonist, glucagon. For 10 points, name this hormone extracted by Frederick Banting that regulates blood sugar levels.
Output (English): Science
