<"Burn" Topic Continued from Last Year!>

I hope you all had a happy winter break. For me, work starts on January
3rd on Tuesday.

I hope my persistence on this question about thermal burns is not
annoying anyone.

Okay. Sorry I didn't use the correct terms.

The red is definitely due to the immune response. It is part of the
inflammatory reaction.

Is the 'whiteness' due to the immune response? I doubt it but I could
be wrong. As I said, my burn injury [from touching a hot plate] looked
white. I am not sure why the injured skin looked white. My thinking is
that the heat damaged the dermal pigments in that area. Once again, I
could be wrong.

I am aware of this. However, in my rules, infection or microbial
decomposition canNOT occur. So if there was no bacterial [or any
microbial] decay, how would the burn look like?

Under my -- too good to be true in today's technology -- rules,
inflammatory reactions also canNOT occur. So how would the burn look
like?

Already know about this. However in my rules, this would not occur. The
injured tissue would either remain a "fresh" wound for life OR it would
spring back to a normal and un-injured state as soon as direct contact
with the open flame is stopped.

Far from it.

I stick with "Green".

If you're going to come up with such a totally fabricated scenario in which 
you are making up your own rules, you can probably justify any colour of the 
rainbow.

ahahahaha.... Why are you obsessing with this? Turn it into fun!:
Do an experiment and then obsess enjoying it, getting your answers
first hand:
Fry an egg!... Ever heard of egg-white? ...observe, conclude, eat!
Fry a fresh, transparent fish- or shrimp piece. ...observe, conclude, eat.

First the transparent proteins denaturate/coagulate and turn white.
Then keep frying and its glyco/sugar type components caramelize
and turn brown, and upon further frying they "char" into black stuff,
wherein an early stage of it (under certain conditions) makes the
fabeled "Dulce-de-Leche" -- for the palate -- ahhhh... mmmhh...
mmmh... ahhh... generated by the Maillard-Strecker reaction as in
the 97,100 google hits for "Maillard reaction" with the executive recipe
in http://www.milk.com/recipes/dessert/dulce-de-leche.html  which
creates this delectable dessert that contains... (so the enviro-shits
will warn you -- to spoil your fun and joy)... these mutagenic Furanoses,
Pyrazines and Aldehydes and Acrylamide... ahahaha.... but be macho
make yourself a batch of "Dulce-de-Leche" and test whether you have
succumbed to the sick, paranoid and fucked up propaganda of the
enviro turds and whether these green shits have been able to even
ruin your desserts..........ahahahahaha.....AHAHAHA.....
Enjoy chemistry...... but fuck enviros!
ahahahaha.......ahahahanson
