It is important to note that,population continues to decrease in rural areas and increase in urban areas.This is attributed to certain factors that are pushing people out of r â¦ ural areas and pulling them to the urban centers.
1 The outer surface of cells is often covered in a polysaccharide or protein material called glycocalyx. 2  Glycocalyx can be formed from protein, polysaccharides, polyalcohols or amino sugars.3  Glycocalyx can function in attachment, protection from desiccation, and protection from attack by a hosts immune system.he general term for any network of polysaccharide or protein containing material extending outside of the cell is the glycocalyx. Many bacteria produce such a coating on the outside of their cell, and they come in two types: capsules and slime layers. The difference between the two is somewhat arbitrary.
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. The polysaccharide structure represents the main storage form of glucose in the body.In humans, glycogen is made and stored primarily in the cells of the liver and the muscles hydrated with three or four parts of water.lycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, but one that is less compact than the energy reserves of triglycerides (lipids). In the liver, glycogen can compose from 5 to 6% of its fresh weight (100â120 g in an adult).
