Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun A copper-containing enzyme of plant and animal tissues that catalyzes the production of melanin and other pigments from tyrosine by oxidation, as in the blackening of a peeled or sliced potato exposed to air.
from The Century Dictionary.
- noun An oxidizing ferment which acts upon tyrosin and leads to the formation of various black substances which are known only in part. The formation of homogentisic acid (alkapton) is probably referable to a tyrosinase. The black pigment secreted by the octopus is produced in this manner.

This sounds like the love child of Tyrone Power and Gary Sinise. Just saying.

Are you suggesting that Gary Sinise is an octopus?
