on the basis of these findings and past studies it is concluded that haemosiderin is an inorganic compound of iron , probably a hydrated ferric oxide and that a variable amount of organic material ( proteins , lipids , phospholipids , etc. , ) probably occurs in company with the haemosiderin in the siderosome , but these variable components which decrease in amount with the passage of time can not be considered as an integral part of haemosiderin .
