| Description | Phosphonoacetaldehyde, also known as 2-oxoethylphosphonate, belongs to the class of organic compounds known as organic phosphonic acids. These are organic compounds containing phosphonic acid. Phosphonoacetaldehyde exists in all living organisms, ranging from bacteria to humans. Phosphonoacetaldehyde 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 a significant number of articles have been published on Phosphonoacetaldehyde. This compound has been identified in human blood as reported by (PMID: 31557052 ). Phosphonoacetaldehyde is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically phosphonoacetaldehyde 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. |
