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 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).Only the glycogen stored in the liver can be made accessible to other organs. In the muscles, glycogen is found in a low concentration (1-2% of the muscle mass).ue to the way glycogen is synthesised, every glycogen granule has at its core a glycogenin protein. Glycogen in muscle, liver, and fat cells is stored in a hydrated form, composed of three or four parts of water per part of glycogen associated with 0.45 millimoles of potassium per gram of glycogen.
