Osazones are a class of carbohydrate derivatives found in organic chemistry formed when sugars are reacted with excess of phenylhydrazine. The famous German chemist Emil Fischer developed and used the reaction to identify sugars whose stereochemistry differed by only one chiral carbon. The reaction involves formation of a pair of phenylhydrazone functionalities, concomitant with the oxidation of the hydroxymethylene group adjacent to the formyl center. The reaction can be used to identify monosaccharides. It involves two reactions. Firstly glucose with phenylhydrazine gives glucosephenylhydrazone by elimination of a water molecule from the functional group. The next step involves reaction of one mole of glucosephenylhydrazone with two moles of phenylhydrazine (excess). First phenylhydrazine is involved in oxidizing the alpha carbon to a carbonyl group, and the second phenylhydrazine involves in removal of one water molecule with the formyl group of that oxidized carbon and forming the similar carbon nitrogen bond. The alpha carbon is attacked here because its more reactive than the others. Osazones are highly coloured and crystalline compounds and can be easily detected. Glucose gives broomstick or needle shaped crystals with this whereas maltose gives sunflower shaped crystals.
[Intro:]
It's another (a murder)
Yow... the one yah name praise
To di father fi all a we days
Gi we life mek we shine bright like di sun raise
Lighter fi bun up all chi chi and gays
Kentiya say di fire muss blaze
Red square tell dem rise up all di AKs
Yeah man, tell dem change them dirty ways
All a who a misbehave, watch yah nuh
[Chorus:]
Well a nuff a dem nah live right so we a bun them now
Waste dem life betta we dunn them now
All who wha fight we have we gun them now
We a bad from a that a stun them now
A who a see di gal them and a run them now
Gal, yo mad- we nah shun them now
Crazy way we set and turn them now

[Verse 1:]
Gal them we love and a we vow that
Father God we put above and a nuh gow that
Nuff man love another man, me nuh see how that
If you a bull and a nuh cow that, betta yo lowe that
We love di gal them and we show that
The gal dem garden we haffi plough that
Nuff see de nable and a guh below that
And a blow that, bredrin betta yo lowe that
Under age yo fi lowe that
Gi Shano and likkle Bow Wow that
Cause a close to death row that
Fifty years yo think a now that, betta yo lowe that
[Chorus:]
That's why haffi bun them now
Waste dem life betta we dunn them now
All who wha fight we have we gun them now
We a bad from a that a stun them now
Rasta man beat di kettle drum them now
Gangsta beat di [? ] dem now
Who a run off di beak and tongue them now
Six feet unda ground them now
[Verse 2:]
Cause man a gangster yo fi know that
You a pass inna di club and me say bredrin
See di war boat and wha fi row that
Me have me glock unda me throw back betta yo lowe that
How you a smoke anuh dro that
And no farmer down a centi nuh grow that
Yo see pan di shotta endz we nuh allow that
A sumn white like snow that? Betta yo lowe that
Money fi mek yah and I know that
But yo nuh fi reap nothing and nuh sow that
How yo fi wha corn and yo neva grow that
Anuh di sweet from yo brow that- betta yo lowe that
[Chorus:]
That's why we haffi bun them now
Waste dem life betta we dunn them now
All who wha fight we have we gun them now
We a bad from a that a stun them now
A who a see di gal them and a run them now
Gal, yo mad- we nah shun them now
Crazy way we set and turn them now
