Description and Uses
Guanine is a crystalline amorphous substance that is found in guano, fish scales, and theliver of certain mammals. Guanine is responsible for the silvery iridescence of certain fishscales. Before its discovery, guanine was scraped from fish scales and used to coat beads to produceimitation pearls. Thus it was called pearl essence or pearly white in the 1700s. Guanineobtained from fish scales is used in cosmetics, especially for eye cosmetics and nail polishes.
