Metabolite Identification
Common Name3-Amino-4-methylpentanoic acid
Description3-Amino-4-methylpentanoic acid, also known as beta-leucine, belongs to the class of organic compounds known as beta amino acids and derivatives. These are amino acids having a (-NH2) group attached to the beta carbon atom. 3-Amino-4-methylpentanoic acid is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on 3-Amino-4-methylpentanoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-amino-4-methylpentanoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Amino-4-methylpentanoic 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.
