Organic acid anhydride
An organic acid anhydride is an acid anhydride that is an organic compound. An acid anhydride is a compound that has two acyl groups bonded to the same oxygen atom. A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride being (RC(O))2O. Symmetrical acid anhydrides of this type are named by replacing the word acid in the name of the parent carboxylic acid by the word anhydride. Thus, (CH3CO)2O is called acetic anhydride. Mixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known.
One or both acyl groups of an acid anhydride may also be derived from another type of organic acid, such as sulfonic acid or a phosphonic acid. One of the acyl groups of an acid anhydride can be derived from an inorganic acid such as phosphoric acid. The mixed anhydride 1,3-bisphosphoglycerate is an intermediate in the formation of ATP via glycolysis, is the mixed anhydride between 3-phosphoglyceric acid and phosphoric acid. Acidic oxides are often classified as acid anhydrides.

You're Ever So Inviting
by: UnderoathThe time has come for you to sit this out
To fit inside your mold
Would be to sell myself short
This ground we tread upon
(We turn the pages left to right)
Is now filling up to our necks
(We see everything)
This ground we tread upon
(We turn the pages left to right)
Is filling up to our necks
(We see everything)
Oh, my story's growing and growing, it is
(On my last request)
Don't make me feel so contradicting
There's no room for cheating and being yourself
Failure leaves such a bitter taste in their mouth
And on the last hour
We write so many new chapters again
And on the outside
Where there are no surprises
This ground we tread upon
(We turn the pages left to right)
Now filling up to our necks
(We see everything)
Oh, it's getting longer and longer, come on
To see it through their eyes
Would bring me so much closer
You can do this night after night after night
Failure leaves such a bitter taste in my mouth
Taste and see, I swear I know what's good
Be still and know that they won't lie to you
Every single time you're facing lies
This ground we tread upon
(We turn the pages left to right)
Is now filling up to our necks
Come on, this ground we tread upon
(We turn the pages left to right)
Is now filling up to our necks
(We see everything)
We see, we see, we see everything
We see, we see, we see everything
I know why you never take your eyes off from me
I've used my lungs for everything but breathing
I know why you never take your eyes off from me
I've used my lungs for everything but breathing
I find myself dried up in this conversation
So pull me out, pull me aside
I find myself dried up in this conversation
So pull me out, pull me aside
This ground we tread upon
(We turn the pages left to right)
This ground we tread upon
(We see everything)
This ground we tread upon
(We turn the pages left to right)
This ground we tread upon
