Metabolite Identification
Common NameRotundic acid
DescriptionRotundic acid, also known as rotundate, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Based on a literature review a significant number of articles have been published on Rotundic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Rotundic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Rotundic acid is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
