ferrittisiin
Ferritin is a globular protein found in all living organisms, serving as the primary intracellular iron-storage protein. It is composed of a protein shell, called an apoferritin, which encases a core of ferric hydroxide-phosphate. This structure allows ferritin to store up to 4,500 iron atoms in a soluble and non-toxic form. The release of iron from ferritin is a tightly regulated process, essential for cellular functions such as DNA synthesis, energy metabolism, and oxygen transport.
In humans, ferritin levels are often measured in blood tests as an indicator of the body's iron
The synthesis of ferritin is regulated by cellular iron levels. When iron is abundant, the cell increases
