C-reactive protein

initialism: CRP
https://doi.org/10.1351/goldbook.12982
Serum protein produced by liver cells as part of the acute-phase response, which acts as a stimulus of the classical pathway of complement activation.
Note: CRP binds to the phosphorylcholine component of the C-polysaccharide, a component of the surface of many bacteria and fungi, resulting in opsonization for enhanced phagocytosis.
