Vanillyl mandelic acid (VMA), official name: hydroxy(4-hydroxy-3-methoxy-phenyl)acetic acid formula: C9H10O5
It is an end-stage metabolite of epinephrine and norepinephrine, the catecholamines.
Urinary VMA is elevated in patients with tumors that secrete catecholamines
Exactly what i want to know to...
No, because one mole of calcium hydroxide constitutes two equivalents of calcium hydroxide for neutralization, but one mole of phosphoric acid constitutes three equivalents of phosphoric acid for neutralization. Therefore, one mole of calcium hydroxide will neutralize only 2/3 of one mole of phosphoric acid.
Not exactly. DNA contains the genetic code; RNA is what transcribes it.
The citric acid cycle, or Kreb's Cycle, takes place within the Mitochondria. Where exactly in the mitochondria is still unknown. We do know that it does take place within the inner spaces of the Mitochondria.
An amino acid links to the tRNA molecule at the binding site called the "aminoacyl site" (A-site) on the tRNA molecule. This process is catalyzed by an enzyme called aminoacyl-tRNA synthetase, which ensures the accurate pairing of the correct amino acid with its corresponding tRNA molecule.
Vanillylmandelic Acid
VMA is the medical abbreviation for vanillylmandelic acid.
this test is used to detect pheochromocytoma, a tumor of the adrenal medulla that secretes excess cathecholamines, epinephrine and norepinephrine,

Not exactly. Acid rain does contain abnormally high amounts of nitric acid and sulfuric acid, but the concentrations are still very dilute.
It can be, yes, depending on what exactly is in the rain.
No, it is exactly opposite - the relative amount of acid in the juice determines the pH.

DNA does stand for deoxyribonucleic acid and you spelled it exactly right.
Not exactly. Acid eats iron through a chemical reaction, but oxidation (rust) is something different.
In acid-base reactions, neutralizing is when you add exactly enough chemical to bring the total solution pH to 7. If you have acid you put alkali in it; for alkali you add acid.
Acidic acid? That's like saying that a fire is a burning fire. Of course f-cking ACID is ACIDic. Are you trying to talk about citric acid? You didn't exactly specify in your question.
