Metabolite Identification
Common NameDitekiren
DescriptionDitekiren belongs to the class of organic compounds known as hybrid peptides. Hybrid peptides are compounds containing at least two different types of amino acids (alpha, beta, gamma, delta) linked to each other through a peptide bond. Based on a literature review a significant number of articles have been published on Ditekiren. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ditekiren is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ditekiren 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.
