What causes bruising

Alot of people mistake bruising for contamination. And they also mistake it for potent mushrooms. Obviously this is not the case.
Im looking for a good explination of what bruising actually is. Why its caused and whats involved.
I read breifly that its an enzyme that causes the brusing and nothing to do with active chemicals.
Anyone care to shed some technical experieence??

I'd like to know too.I find that the handled cubes form a yellowish,brown area and then bruises to blue,green or black.It's not the actives that are burning up though.I had two similar fruit bodies from a cluster and the one handled was no less potent then the one i snipped off at the base.

Bump
after more research im not convinced its an enzyme
AFter a post over at shroomotopia sparced more reasearch this is what i posted

Psilocybin is a naturally-occurring compound found in varying concentrations in some species of the genera of Psilocybe spp. and Panaeolus spp. (fungal Phylum Basidiomycota). The spores of these mushrooms are completely free of both psilocybin and psilocin. Mushroom caps tend to contain more of the psychoactive compounds than the stems.[4][5][6] The total potency varies greatly between species and even between specimens of one species in the same batch.[7] Younger, smaller mushrooms are relatively higher in alkaloids and have a milder taste than larger, mature mushrooms. Mature mycelium contains some psilocybin, while young mycelium (recently germinated from spores) does not contain appreciable amounts of alkaloids.[8] Many species of mushrooms containing psilocybin also contain small amounts of the psilocybin analogs baeocystin and norbaeocystin.[9][10][11] Most species of psilocybin-containing mushrooms bruise blue when handled or damaged[12] due to the oxidization of phenolic compounds. This is not a definitive method of identification or determining a mushroom's potency.
There are other species of mushrooms that bruise blue which are not active.
Phenolic compounds are compounds with a hydroxide group attached to aromatic hydrocarboms. for example phenol.
Hmm, now im just confused. At first glance of that, it apears that its not the actives oxidising but other chemicals. then a search on phenolic compounds
Quote:
n organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of a hydroxyl group (-O H) attached to an aromatic hydrocarbon group. The simplest of the class is phenol (C6H5OH). Phenol - the simplest of the phenols.
Although similar to alcohols, phenols have unique properties and are not classified as alcohols (since the hydroxyl group is not bonded to a saturated carbon atom). They have relatively higher acidities due to the aromatic ring's tight coupling with the oxygen and a relatively loose bond between the oxygen and hydrogen. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12). Loss of a positive hydrogen ion (H+) from the hydroxyl group of a phenol forms a negative phenolate ion.
im all confused now, psycolibin has an aromatic hydrocarbon but its not directly conectect with the hydroxyl group, dont know much about chemistry.
The 2 anologhe chemicals also have a similar structure with the hydroxyl group not directly attached to the aromatic hydrocarbin
beaocystin
norbeaocystin
to early for all this thinking/reasearching
Im gonna slap the person who suggested it was an enzyme that causes the bruising

The Blueing Reaction. "Only psilocin can be oxidized into products of bluish-green colour (GARTZ, 1996). The phosphate group in psilocybin and baeocystin prevents direct oxidation of the alkaloids. However, the typical blueing phenomenon does occur when this protective group is removed by enzymes, such as various phosphates, which are very common also in mushroom tissue. Apparently, the enzymatic removal of the phosphate group from the psilocybin occurs quite quickly. This is how psilocin is formed after injuries of the fruit bodies. Immediately after wards psilocin continues to break down into blue-coloured compounds."

Mr Gartz should(and does) know better than that. Many species of Bolete bruise blue/green and they're non-active. RR

If you click on the link it talks about similar bruising in other species and how its caused by a different compound.
Gartz was referring what causes bluing in Psilocybe mushroom in particular.. In other words..There is nothing else in the Psilocybe mushroom that would cause the bluing.
I hope thats clearer.
