| Common Name | 2-Aminoacetaldehyde |
|---|
| Description | 2-Aminoacetaldehyde belongs to the class of organic compounds known as monoalkylamines. These are organic compounds containing an primary aliphatic amine group. 2-Aminoacetaldehyde 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 2-Aminoacetaldehyde. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-aminoacetaldehyde is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Aminoacetaldehyde 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. |
