. Oligosaccharides are composed of a saccharide polymer with multiple monosaccharide chains. These are usually located within the plasma membrane and are involved in cell-to-cell recognition. They are used as a external marker in the health care field, as these are found to be made up of components of glycoproteins/glycolipids. An example is a patient with ABO blood type specificity, specifically patients with blood type A and blood type B, as they have been examined to have two different oligosaccharides, which are the glycolipids located on the cell membrane of red blood cells. Patients with Blood type O will show neither of these glycolipids on the surface of the RBC, while AB blood type will show both, respectively
Some examples of polysaccharides are as followed:
Starch and amylose, energy storage, plants
cellulose, forms the cell walls in plants
Monosaccharides, like DNA and RNA, form critical portions of our genetic makeup and help us pass on the blueprints of our genetic makeup to our children.
