There are two forms of scleroderma: localized scleroderma (primarily affects the skin, most common form found in children) and systemic sclerosis (a chronic, degenerative disease rarely seen in children). Linear scleroderma is a progressive loss of subcutaneous fat with pigment changes in the skin.
We assume that the person described here starts the work period eagerly, using stored glycogen at the beginning of the work session. Muscle glycogen remains is the major source of energy during the first half-hour. After this period we see that fatty acids and blood glucose takes over as important energy sources.
Glycogen is the storage form of glucose, the source of human energy derived from carbohydrates consumed through food. To assist in the storage process, molecules of glucose, a sugar composed of carbon, oxygen, and hydrogen atoms, are strung together to form glycogen, a complex molecule known as a polysaccharide.he skeletal muscles and the liver are the two chief storage facilities for glycogen. Approximately 1% of muscle mass is glycogen; between 8% and 10% of the liver's weight is stored glycogen. The skeletal muscles store two times as much glycogen as does the liver.
