Metabolite Identification
Common NameLeukoaminochrome
DescriptionLeukoaminochrome, also known as 5,6-indolinediol or indoline-5,6-diol, belongs to the class of organic compounds known as indolines. Indolines are compounds containing an indole moiety, which consists of pyrrolidine ring fused to benzene to form 2,3-dihydroindole. Leukoaminochrome is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on Leukoaminochrome.
