C-reactive protein was discovered and named for its binding to pneumococcal somatic C-polysaccharide  in which it recognizes the phosphocholine residues which are present in this ribitol teichoic acid . Phosphocholine is the natural ligand to which CRP binds with highest affinity and this key ligand is ubiquitous as the polar head group of phosphatidlyl choline in cell membranes and plasma lipoproteins. Phosphocholine is also present in constituents of many bacteria, fungi and parasites and plants and the importance for mammalian biology of its recognition is exemplified by the fact that a significant proportion of the germline antibody specificities are directed at it. However, CRP does not bind to all materials containing phosphocholine as the residues must be 'available' or in an appropriate sterochemical configuration. Thus CRP binds to dead or damaged cells in which significant amounts of lysophosphatidyl choline are present, but not the surface of living healthy cells . Binding of CRP to apoptotic cells is controversial and the most rigorous evidence suggests that CRP only binds to so-called late apoptotic cells which are effectively necrotic [32–34]. CRP also binds to oxidized phospholipids , platelet activating factor , modified LDL , β-VLDL, concentrated normal VLDL  and to small nuclear ribonucleoprotein particles (which do not contain phosphocholine) when these are exposed in dead or damaged cells [38, 39].
That and watch the dog. I was an English major, for crying out loud. I think my brain just went necrotic.
