Alien molecules

The sole function of many proteins is simply to bind other molecules. Thus, immunoproteins are able to bind to alien molecules (antigens) and destroy their activity by complexation. Some proteins act as hormones, influencing metabolic rates by binding to another molecule or stmcture. Binding to a protein may be the way an organism transports a... 

The phenomenon of immune privilege was initially described by Dooremal in 1873 (van Dooremal, 1873). He noticed that tumor cells injected into the AC of the eye formed growing tumors unlike tumor cells injected into skin or other organs. Meclawar discovered that transplants between genetically different incUviduals usually were destroyed due to the ability of the immune system to detect alien molecules on the graft. However, skin grafts placed in the AC of the eye and in the brain of rabbits survived much... 

The possible existence of Huxley s mysterious, timeless regions of reality has led professional and amateur researchers to ponder the extraordinary effects of the DMT molecule (N,N-Dimethyltryptamine). DMT is a psychoactive chemical that causes intense visions and coaxes users to quickly enter a completely different world that some have likened to an alien or parallel universe. DMT is a chemical produced in our own bodies and by many plants. Daniel Pinchbeck in Breaking Open the Head says, smoking DMT is like being shot from a cannon into another dimension and returning to this world in less than ten minutes. The transition from our world to the DMT universe ( DMTverse ) oc-... 

Add to cube file ADD TO CF) This option adds the molecule to the cube file it first checks to see If the molecule has already been aliened. 

The introduction into the organism of an alien substance antigen) of sufficient molecular weight (M> 5000 Da), provokes the production of bio-molecules called... 

Another idea, alien to theoretical chemistry at the time but nevertheless useful to chemists, was the idea of struaural comparisons of molecules by the... 

It seems appropriate to discuss here the probabUity of interpenetration of polystyrene coils in the model networks. As already mentioned, according to the theoretical considerations of Flory [138] and De Gennes [139], polymeric coils in an amorphous solid state retain unperturbed dimensions. Since the volume fraction of the polymer in an unperturbed coil under -conditions is weU known to be very smaU, only about 2%, the transition from swoUen coils to solid state has to be accompanied by the replacement of aU solvent molecules with fragments of other polymeric molecules. In other words, theoretical notions predict extremely high mutual interpenetration of the polymeric chains in bulk state. Indeed, in order to maintain the coil dimension that is characteristic for a -solution, the coil must accommodate, on removing the solvent, a 50- to 100-fold amount of alien polymeric matter. In the 1970s this problem was discussed in fiiU [149-165], The authors of the tailor-made networks also took part in the discussion. 

As mentioned above, in the absence of alien components H O molecules are positioned in a certain order, forming their own structures, similar to a tetrahedron. Moreover, the strength of these structures and orderliness of the O and H atoms decrease with the growth in temperature. 

Antigen, namely, an alien cell, everything which is not physical things will be probably antigen, for example, pathogen, pollen, a transplanted organ. Antibody is able to swallow the antigen. The molecule of antibody is a kind of protein, for example, white blood cell.
