Polyamine
A polyamine is an organic compound having two or more primary amino groups –NH
2 as cations.
Low-molecular-weight linear polyamines perform essential functions in all living cells. Primary examples are putrescine, cadaverine, spermidine, and spermine. In animals, their levels are maintained from both the diet and de novo synthesis, and their decline with age is associated with various pathologies. Polyamine metabolism is regulated by the activity of the enzyme ornithine decarboxylase (ODC). Polyamines are found in high concentrations in the mammalian brain.
This class of compounds also includes several synthetic substances that are important feedstocks for the chemical industry, such as ethylene diamine H
2N–CH
2–CH
2–NH
2, 1,3-diaminopropane H
2N–(CH
2)
3–NH
2, and hexamethylenediamine H
2N–(CH
2)
6–NH
2. Certain polyamines are employed on industrial scales as co-reactants (hardeners) with epoxy resins.
As of 2004, there had been no reports of any geminal diamine, a compound with two or more unsubstituted –NH
2 groups on the same carbon atom. However, substituted derivatives are known, such as tetraethylmethylenediamine, (C

Spring It On 'em
by: BlowmenMe and my mates went out to the bar
Just to see who the drunken saps are
Pathetic little people to the left and right
We can't get blamed if they forget the night
After one round o' drinks I can pretty much tell
My mates are ready to raise some hell
They won't know what hit 'em when we run amok
SPRING IT ON 'EM WHEN THEY'RE DRUNK AS FUCK!

Me and my mates were at a bar mitzvah
The open bar must have cost a little extra
In honor of entering his manhood

My mates decided to make 'em oy vey
We tried throwin' bagels and the bagels stuck
SPRING IT ON 'EM WHEN THEY'RE DRUNK AS FUCK!
We found some hummus and we launched that muck

We went to a shindig with the bourgeoisie
The place was stuffy but the drinks were free
They looked at us funny when we started to cuss
What makes those pricks think they're better than us
While they sip glasses of wine and champagne
Me and my mates are goin' half insane
Tell the host that the hors d'ouvres suck
SPRING IT ON 'EM WHEN THEY'RE DRUNK AS FUCK!
The rich girls here could use a tummy tuck
SPRING IT ON 'EM WHEN THEY'RE DRUNK AS FUCK!
