5,6-dihydroxyindole-2-carboxylic acid (DHICA): a First Principles Density-Functional Study
, 2004 We report first principles density functional calculations for 5,6-dihydroxyindole-2-carboxylic acid (DHICA) and several reduced forms. DHICA and 5,6-dihydroxyindole (DHI) are believed to be the basic building blocks of the eumelanins.
