Hemomelanin

Hemomelanin is a substance isolated from cuttlefish ink; brown-red pigment, a product of bilirubin oxidation. Produced by hemocyanin (hemocrorin) and hemoglobin. Blood and skin of many shellfish.

The mechanism of formation of membanin is different from melanin. Hemomelanins are produced on the membrane of cellular organelles - this is evidenced by the cytoplasmic location of hemomelanin in tissues and its discontinuous structure (many balls of melanin substance isolated from the melanin pigment granule). In this form (in the form of spots) melanin is concentrated
