Chromoproteid

**Chromoproteins** are specific proteins that contain pigments and are a complex group of biologically active substances that promote or prevent the occurrence of various biochemical reactions (for example, in metabolism, photosynthesis, regulation of membrane activity, mechanism of tissue hematopoiesis).

Chromoprotectin, so named due to its ability to stain tissue, is presented in the form of either whole molecules or fragments. In this case, the chromoprotein in solution is colorless or transparent, and in tissues it forms complex complexes with white
