This system is important in evaluating candidate molecules to treat or prevent debris-associated osteolysis and loosening of prostheses . One end of the dumbbell-shaped molecule is customized to bind to the protein of interest ; the other end homes in on the cell ’ s natural protein-degrading apparatus . The vectors of communication in biological systems are protein molecules , which are specified by strings of nucleotides on the chromosomes . These frequencies are unique to each molecule , and provide a " fingerprint " in the electromagnetic spectrum . The scale is set to it default value , zoom 100 , the centre of rotation is set to the geometric centre of the currently loaded molecule , centre all , this centre is translated to the middle of the screen and the viewpoint set to the default orientation . This radiation hits oxygen molecules in the upper stratosphere and converts them to ozone . Glucose and other carriers are absorbed across the brush border of the epithelial intestinal cell by an active mechanism , in the course of which a molecule of sodium , linked to a molecule of glucose , is carried into the cell .
