Complex sentence: Inhibitors of G6PT1 are the most studied as this subunit holds the greatest promise as a drug target for disease treatment, as it catalyzes the rate limiting step in glucose production through gluconeogenesis or glycogenolysis and thus without its function, these two processes cannot occur.
