Fatty acid metabolism months, and, during this entire period, the energy is derived from degradation of fat stores. Migrating birds similarly build up large fat reserves before embarking on their intercontinental journeys. Thus the young adult human’s fat stores average between about 10–20 kg, but varies greatly depending on age, gender, and individual disposition. By contrast the human body stores only about 400 g of glycogen, of which 300 g is locked inside the skeletal muscles and is unavailable to the body as a whole. The 100 g or so of glycogen stored in the liver is depleted within one day of starvation.
Glycogen storage disease type II International Pompe Association. John Crowley became involved in the fund-raising efforts in 1998 after two of his children were diagnosed with Pompe's. He joined the company Novazyme in 1999, which was working on enzyme replacement treatment for Pompe's. Novazyme was sold to Genzyme in 2001 for over US$100 million. The 2010 film "Extraordinary Measures" is based on Crowley's search for a cure. Glycogen storage disease type II Glycogen storage disease type II, also called Pompe disease, is an autosomal recessive metabolic disorder which damages muscle and nerve cells throughout the body. It is caused by an accumulation of glycogen in
