Speaking in general terms, mitochondria is known as the powerhouse of the cells. Within these mitochondria, is a minute hemeprotein that is found within the inner membrane known as Cytochrome-C. Belonging to a family of proteins, this is highly soluble in water and is an important part of the transport chain of electrons. Though oxidation and reduction are an important part of it, however binding of oxygen is not quite a job of this protein. Within this Cytochrome-C protein, there occurs a transition within states of ferrous and ferric that makes it sure that an important role is played in plants and animals likewise. It also has a very important role to play as biological electron transferor in bodies.

There are a number of functions that are specific to this protein, some of them being its important role in apoptosis. This Cytochrome-C is used specifically for detecting infections in DNA as well as its role in death of cells. Binding the cardiolipin to the inner membranes of mitochondria, this helps in initiating the process of apoptosis. However, as per latest reports based on tests done by Mouse Cytochrome-C (CytC) ELISA Kit, this protein is useful for stopping this process of apoptosis both in humans and bovine creatures. This also acts as antioxidative enzyme in bodies.
