Metabolite Identification
Common NamePasakbumin-A
DescriptionPasakbumin-A belongs to the class of organic compounds known as quassinoids. These are a group of compounds chemically degraded from triterpenes. According to their basic skeleton, quassinoids are categorized into five distinct groups, C-18, C-19, C-20, C-22 and C-25 types. The C-20 quassinoids can be further classified into two types, tetracyclic and the pentacyclic. The tetracyclic variety does not have oxygenation at C-20, while the pentacyclic quassinoids possess additional oxygenation at C-20 that allows for the formation of an additional ring. Based on a literature review a significant number of articles have been published on Pasakbumin-A. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pasakbumin-a is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pasakbumin-A 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.
