| Common Name | Enniatin A |
|---|
| Description | Enniatin A, also known as antibiotic 86-88 or enniatins, belongs to the class of organic compounds known as cyclic depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids) connected in a ring. The residues are commonly but not necessarily regularly alternating. Enniatin A is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Enniatin a is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Enniatin 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. |
