Metabolite Identification
Common NameSemax
DescriptionSemax belongs to the class of organic compounds known as oligopeptides. These are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. Based on a literature review a significant number of articles have been published on Semax. This compound has been identified in human blood as reported by (PMID: 31557052 ). Semax is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Semax 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.
