Cytochrome

Cytochromes are redox-active proteins containing a heme, with a central Fe atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding. Four varieties are recognized by the International Union of Biochemistry and Molecular Biology (IUBMB), cytochromes a, cytochromes b, cytochromes c and cytochrome d. Cytochrome function is linked to the reversible redox change from ferrous (Fe(II)) to the ferric (Fe(III)) oxidation state of the iron found in the heme core. In addition to the classification by the IUBMB into four cytochrome classes, several additional classifications such as cytochrome o and cytochrome P450 can be found in biochemical literature. more »

Call me crazy
The sky looks hazier than yesterday
No children playing
Swing set swaying
The winds of winter carry only fire and flames.
I pray for rain
But my heart just ain't in it
I cannot build a shelter out of thoughts alone.
No way to spin it
Gone one too many miles down a one way road.

Hills of angels
Wings singed and tangled
The Queen herself came down before the shadows throne.
She stands pleading
"Our future's bleeding"
Had enough still fill the cup that's how we roll.

So what's it going to be
The thunder or a whisper
Not a soul out on the street
So hot my sole begins to blister
We keep on searching for the key
To unlock the clock and turn back history
Who's left to bow now that the crown is melting down

Whoah
I want to know how far your followers will go
Whoah
I want to know how far your followers will go

So what's it going to be
A whisper or the thunder
Who'll be standing at the bridge
When the ship is slipping under

Whoah
I want to know how far your followers will go
Whoah
I want to know how far your followers will go
Whoah
I want to know how far your followers will go
Whoah
I want to know how far your followers will go
