hemosiderin

 [he″mo-sid´er-in]
a pigment that is a product of hemolysis; it is an insoluble form of storage iron that is visible microscopically both with and without the use of special stains.

he·mo·sid·er·in

(hē'mō-sid'ĕr-in),
A golden yellow or yellow-brown insoluble protein produced by phagocytic digestion of hematin; found in most tissues, especially in the liver, spleen, and bone marrow, in the form of granules much larger than ferritin molecules (of which they are believed to be aggregates), but with a higher content, as much as 37%, of iron; stains blue with Perls Prussian blue stain.
[hemo- + G. sidēros, iron, + -in]

hemosiderin

/he·mo·sid·er·in/ (he″mo-sid´er-in) an insoluble form of tissue storage iron, visible microscopically both with and without the use of special stains.

hemosiderin

(hē′mō-sĭd′ər-ĭn)
n.
An insoluble protein that contains iron, is produced by phagocytic digestion of hematin that is released during hemolysis of hemoglobin, and is found as granules in most tissues, especially the liver.

hemosiderin

[hē′mōsid′ərin]
Etymology: Gk, haima + sideros, iron
an iron-rich pigment that is a product of red cell hemolysis. Iron is often stored in this form. Also spelled haemosiderin.

he·mo·sid·er·in

(hē'mō-sid'ĕr-in)
A yellow or brown protein produced by phagocytic digestion of hematin; found in most tissues, but especially in the liver; at higher levels, it stains blue with Perls Prussian blue stain.
Synonym(s): haemosiderin.

hemosiderin (hē´mōsid´ərin),

n an intracellular storage form of iron; the granules consist of an ill-defined complex of ferric hydroxides, polysaccharides, and proteins having an iron content of approximately 33% by weight. It appears as a dark yellow-brown pigment.
