vedr. den blånende reaktion i Gyroporus cyanescens.
Citat:
The blueing reaction is easily explained through biochemistry. A compound called variegatic acid remains colorless unless it is exposed to oxygen. The cell walls of Gyroporus cyanescens are easily broken, exposing the variegatic acid to the air. The oxygenase enzyme converts the variegatic acid to its quinone methide, which is blue. Interestingly, in many other boletes, in the absence of oxygen, variegatic acid is converted to variegatorubin, which is responsible to the red color found in many members of this group.
Chemists have tried to identify the chemical responsible for the blue color in psilos, and suprisingly haven't been able to pin it down. A quinone is a likely candidate for this pigment also, since their their alternating single and double bonds trap certain wavelengths. However, that will be determined by some future study.
What convinces me that psilocin oxidation is responsible for the blue color is that those psilos that don't stain blue are low in psilocin content and vice versa. How that relates to your original question is that if psilocin is the precursor to the 'blue chemical', then yes, some active is lost when you see bluing. Since scientists haven't even pinned down the mechanism, however, the amount of magic lost is totally unknown. But, I would be cautious about activities that exaggerate this bluing, such as physical bruising, freezing, and anything else that can expose large amounts of intracellular fluids to the atmosphere.
Okay, måske er "inficeret" så ikke det helt rigtige ord. Fik måske simpliceret det lige lovligt meget. Sorry.
