A steroid is an organic compound with four rings arranged in a specific configuration. Examples include the dietary lipid cholesterol, the sex hormones estradiol and testosterone and the anti-inflammatory drug dexamethasone. Steroids have two principal biological functions: certain steroids (such as cholesterol) are important components of cell membranes which alter membrane fluidity, and many steroids are signaling molecules which activate steroid hormone receptors.
The steroid core structure is composed of seventeen carbon atoms, bonded in four "fused" rings: three six-member cyclohexane rings (rings A, B and C in the first illustration) and one five-member cyclopentane ring (the D ring). Steroids vary by the functional groups attached to this four-ring core and by the oxidation state of the rings. Sterols are forms of steroids with a hydroxyl group at position three and a skeleton derived from cholestane. They can also vary more markedly by changes to the ring structure (for example, ring scissions which produce secosteroids such as vitamin D3).
even lady luck
she said she could not help
she's just a dead end queen
keep her away from me
she said, "keep her away from me,
i don't even like to see her breathe
i can't stand staring at the face of me
girl, stay away from me"
she's not the kind that you want to be seen with
she's the dead end queen, she's the dead end queen
she's a dead end queen
she's not the kind that you want to be seen with

get close enough to use my telepathy
i'll drain a little piece of you into me
then, i won't get shot
she's a dead end queen
she's not the kind that you want to be seen with
she's the dead end queen, she's the dead end queen
oh no, she's a dead end queen
she's not the kind that you want to be seen with
she's a dead end queen, she's a dead end queen
take it, take it all away
take it, take it all away from her
take it, take it all away
take it, take it all away from her
oh NOOOO
oh NOOOO
oh NOOOO
she's a dead end queen
she's not the kind that you want to be seen with
she's the dead end queen, she's the dead end queen
