Metabolite Identification

Common Name

Octanamide

Description

octanamide, also known as caprylamide, belongs to the class of organic compounds known as fatty amides. These are carboxylic acid amide derivatives of fatty acids, that are formed from a fatty acid and an amine. Based on a literature review very few articles have been published on octanamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Octanamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Octanamide 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.

Enzyme Details

1. Peptidyl-glycine alpha-amidating monooxygenase

General function:: Involved in monooxygenase activity
Specific function:: Bifunctional enzyme that catalyzes 2 sequential steps in C-terminal alpha-amidation of peptides. The monooxygenase part produces an unstable peptidyl(2-hydroxyglycine) intermediate that is dismutated to glyoxylate and the corresponding desglycine peptide amide by the lyase part. C-terminal amidation of peptides such as neuropeptides is essential for full biological activity.
Gene Name:: PAM
Uniprot ID:: P19021
Molecular weight:: 108402.425
