Polysaccharide of moving animals. Cellulose and chitin are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms, and is said to be the most abundant organic molecule on Earth. It has many uses such as a significant role in the paper and textile industries, and is used as a feedstock for the production of rayon (via the viscose process), cellulose acetate, celluloid, and nitrocellulose. Chitin has a similar structure, but has nitrogen-containing side branches, increasing its strength. It is found in arthropod exoskeletons and in the cell walls of some fungi. It also has
Glucose 6-phosphatase a highly conserved residue that completely destroyed G6PT activity. These mutations lead to the prevalence of GSD-1 by preventing the transport of glucose-6-phosphate (G6P) into the luminal portion of the ER and also inhibiting the conversion of G6P into glucose to be used by the cell. The third type of glucose-6-phosphatase deficiency, glucose-6-phosphatase-β deficiency, is characterized by a congenital neutropenia syndrome in which neutrophils exhibit enhanced endoplasmic reticulum (ER) stress, increased apoptosis, impaired energy homeostasis, and impaired functionality. It can also lead to cardiac and urogenital malformations. This third class of deficiency is also affected by a G6PT deficiency as
