Binary Data hot_stuff.mwc

Capsaicin is a chemical made by chili peppers that contributes to a sensation of heat.

Binary Data capsaicin.sdf.gz

Capsaicin receptor, also called the TrpVI Ion channel.

Binary Data 3J5P.cn3

Capsaicin receptor bound to spider toxin.

Binary Data 3J5Q.cn3

The "double-knot" spider toxin binds to the TrpV receptor and causes a sensation of heat and pain.  

Binary Data Huwentoxin.cn3

TrpA1 ion channel.  Allyl isothiocyanate from wasabi binds to this receptor and causes a sensation of heat and pain.

Binary Data 3J9P.cn3

Allyl isothiocyanate is the chemical in wasabi that creates a sensation of heat.
